I'm sorry this happened to you, but it highlights another very important factor. Don't keep all keys to the kingdom on one person. Always divide and conquer. Keep power distributed between multiple people. I worked at a company of 500+ people, and I'm sure the CEO didn't have access to all the IT people's stuff. They only cared that everything works and meet their quarterly goals. Shall the IT person feel like sabotaging stuff, there are distributed backups and mainly the fine print in the work contract preventing that.

I know this doesn't necessarily apply to smaller companies and startups, but have lawyers write you strong contracts that aren't one-sided, but are full of protections for both sides, if they aren't sabotaging stuff.

This, yes, but there’s a really interesting corollary:

If you’re on a small team (~5 people) the person obsessed with access controls cannot be trusted.

First of all, thank you! Updated the title ;)

See, this is my problem when I start to think about stuff. I always take it from the most complicated angle. I didn't look at it as Bluetooth headphones that record stuff directly.

No worries!

Also searching for "iphone call recording" on your marketplace of choice like amazon, also shows many results including usb dongles which act as a bluetooth dongle as far as I understand.

I neither own an iPhone nor any of these devices, so I can't tell how usable all these devices are!

Probably a middle man bluetooth device which you would connect via bluetooth from the iPhone, which then connects to a bluetooth headset could add a noticable delay, but I haven't seen such a device (maybe because of that exact reason)

The situation is even worse here at your SE neighbors. The three nation wide ISPs don't provide working IPv6 at all:

Slovak Telekom (Deutsche Telekom Subsidiary, same as Czech T-Mobile/T-Com) - FTTx, DSL, WISP

Orange (French Orange S.A. subsidiary) - FTTx, DSL, WISP

O2 (The Czech HQ'd PPF owned, not the UK one) - WISP

And even the more regional, but still big, aren't much better.

UPC (Liberty Global subsidiary) - Cable

Antik (Slovak company) - FTTx, Cable, WISP

SWAN (also Slovak company) - DSL, FTTx, WISP

But I have to shout out my dad's ISP, it's called RadioLAN, it's a slovak company, provides WISP and FTTx and also IPv6 to everyone by default. So far the only one I've found. Funny thing is, the peering in our country is handled by two IXs: SIX and NIX both natively supporting IPv6 interconection. If I've messed some terminology or I've outdated info, I'm sorry. As you said, nod to until we live in a very very specific location, we're left with just one ISP, or basically the same one in blue. I'm less than 10km behind the capital's outer borders, yet I have a huge problem getting FTTH ran here. It's literally connected at the both ends of our street, just not here. I've considered doing something about it myself, it's just simply too expensive.

It's not that bad (this was situation some time ago, might be even better today):

Orange does support IPv6 on FTTH and DSL (do not know about mobile network); they use DS lite and allow user port mapping for IPv4 (!), provide /56 by default. They didn't migrate existing customers, they just started with new ones (2016 for DSL, 2018 for FTTH), which is reasonable. There's also an issue with IPTV service, which runs over IPv4 multicast, so new customers with TV service (or those who ask explicitly) get IPv4-only anyway.

UPC (Liberty Global) has exactly the same issue as the Czech one: DS lite and you get /64 only. It is the same design, shared by all UPCs, (the Czech one is just a recent acquisition from them by Vodafone).

Slovak Telecom "is planning" (since 2020). TBH, I would expect ST to get rid of PPPoE on FTTH first ;)

Swan supposedly supports IPv6 now, at least in their core. They claim IPv6 support in their materials (at least in those communicated to business customers).

Note that ST/Orange/O2 are not WISPs; they are mobile networks. With WISP, the understanding is that they would use wireless radios like Radiolan does (i.e. Radiolan is WISP).

> I'm less than 10km behind the capital's outer borders, yet I have a huge problem getting FTTH ran here.

This is common and not that surprising. If you check availability for the FTTH in the capital's city center, you will find that the situation is the same (or similar: chances are, that the end of the street is not connected). It is residential areas with high density that have the good coverage.
