> Could you point me to a couple videos of Czech JB devs talking at Czech conferences in Czech?
Do you have examples of them not talking Czech at Czech conferences? Not talking a particular local language at an international conference is not a significant metric IMO. A great many companies from all over the world send people out to speak English (or at least American!) at conferences. As a linguistically ignorant Englishman this is rather useful to me, but it doesn't make those companies not French, not German, not Indian, not Chinese, etc.
Heck, if (caveat: speculation, I've not looked into this at all) Russian is a common enough second language in the country (or at least amongst local+visiting delegates for conferences about these subjects) then some talks at a conference in the Czech Republic being in Russian would not be surprising, much like you see many talks in English/American countries where English is not an official language (and similar for other languages that are significantly more common if you count people with them as second+ languages as well as native speakers).
> used to listen to tech podcasts
The issue is more acute with podcasts than conferences: the audience is international, so they might not have the luxury of using their native language while serving a large enough target audience.
> Because I was a russian speaking … listen to tech podcasts and talks in russian all the time
I see much room for confirmation bias here. What reason would they have, beyond national pride which is valid of course, to make a point of explaining “we aren't Russian BTW” on a Russian language podcast? Especially give that could be seen as a bit of a down-play of the Russian audience if national pride works the other way against them.
