Imo, arduino is also mostly a software project nowadays. While they did make a bunch of avr boards that were quite novel and interesting at the time, now they are not as good in terms of both price and performance compared to various arm-based boards.
What keeped arduino alive is a bunch of libs and arduino ide cores for various boards ppl have written over time.
TA just didn't fit my use case when I tested it, tbh: I mainly wanted to expose a dozen or so YouTube channels as podcasts to antennapod while saving the audio and stripping integrations with sponsorblock.
Mostly because compilers do this kind of stuff if you optimize for space, iirc. Not that you should never do it or something, but it kinda looks like premature optimization to me.
Signal is the most user-friendly option so far, which is also expected, given it's also one of the oldest one of those.
Simplex is also a good-ish option, but somewhat rough around the edges; the biggest benefit is, one doesn't need a phone number or e-mail to start chatting.
Matrix is questionable: it's quite feature-rich, but lacks solid android clients (IMO, fluffychat is among the best so far, yet when I last used it, it didn't handle stickers/custom emojis all that well, for example); as for the desktop/web clients cinny is a godsend due to allowing importing/exporting encryption keys manually, which just works all the time.
It's kinda the same as it was before, as far as I can see, for the personal plan. Looks like they've just added more the ability to add more than 3 users for a fee.
Not sure if it was a joke 😅 Nextpush uses your nextcloud (~a self-hosted google drive alternative) instance in case you happen to have one, so that would depend on where you're hosting it. Although, assuming push notifications aren't exactly resource-intensive (otherwise those would require at least making an account), the difference would be pretty negligible from a performance standpoint
