Indeed, as the other comment stated, it’s the reliance on phone numbers.

• Governments can intercept and block registration SMS and put you straight on the watchlist for even trying
• Every single cell provider in the world can make phone calls from your number, nevermind sms, and so does everyone who has influence over them, be it law enforcement, someone with money or inside connections to bribe some corrupt employee, or just a kid with a gsm sniffer, or even just a sharp tongue and gall to just call them and say “Hey my name is Bob Marley, unfortunately I’ve lost my phone, could you send me a new one with the same number”. Yes, they won’t be able to read your messages, but they can register a new account to your number and scam your friends by pretending to be you.
• Privacy nightmare, phone numbers carry a lot of private data with them which is very easily doxx-able. I don’t want to share all that just to chat with someone, especially when supposedly talking about something I wouldn’t want someone else to be prying upon. IE if I’m planning a crime I don’t want my potential accomplices to know my full legal name and DOB, which they’d be able to get for just a dollar if they knew my number.
• How do you even deal with spam? Admittedly I’ve never used Signal, because of point 1 where government blocked and put me on the watchlist, but in a similarly phone-tied telegram, when my p/n got leaked I got dozens of spam messages every day from random accounts, and had to basically abandon it because there’s no easy way to change the identity

Given that there are amps and AIO synth, I assume this is meant to be a high school band rehearsal place? Then the drummer should already have that place’s kit set up for him, it’s not like they can even afford their own, nevermind the bags for it.

Signal sucks, tho. Use Session instead. Or SimpleX. Or Delta Chat. Or Matrix…

Federation is kinda clunky, there is no way to see content posted before you federated, same with upvotes, so top of all time is different across communities. But most annoying of all is that to see the communities you have to paste the full link into search. Big instances can rely on some of the users doing it but for single user instance you have to go to bigger instances and see their list of communities and copy-paste the links into your instance search bar, otherwise you cant see any new posts from those.

Selfhosting, yeah!

actually selfhosting lemmy kinda sucks don’t bother unless you have to
