Not my groups, owned by non-technical users, so I doubt they will accept that suggestions. Everybody uses Whatsapp here, so it's the path of least resistance.

Anyway, I don't believe this is going to last, unless Telegram itself decides to leave Spain. They've ignored a court request for information, not even a takedown request and they're now learning that they can't do that.

People is resorting to the app's built-in proxies, but if Telegram doesn't answer, I'm afraid that hole will be fixed too.
