the connecting with a majority of people using the same closed source platform
The platform is open, including the part that connects to other closed source platforms. It's just Matrix and open source bridges after all. And making the client app closed souce doesn't help with any of that.
I'm sorry if I'm a bit pedantic about this, but it seems like you're describing an upside to closed source software that's just not there.
You're definitely right that people are a bit too doom-and-gloom about it, Beeper did do a lot of good over the last few years!
But I also find it a bit odd that they talk so much about the importance of open source in messaging, and then release a closed source client without at least adressing the topic. Add the fact that they've been aquired by another company on the same day, and it starts to smell like another instance of openwashing.
The thing is, we are talking about the Beeper service here. Yes Matrix is good, yes Beeper bridges are good, but a closed source Beeper app is bad. That's what the criticism is about, and it doesn't help if you deflect that by arguing about all the other things they are doing or that no one is forced to install it.
What is this "closed source experience" you are talking about? How would making the client open source hinder that in any way, especially when their stated goal is to earn money with premium features instead of the app itself?!
Imo being open source is a VERY big deal for an e2e encrypted chat client! I don't really care whether most of their stack is open if the app I'm actually using to type and encrypt my messages is not. This makes the whole thing look like a trick, pretending to be open when key parts are not.
It's a knownissue and should be fixed in the most recent version of Piped (and probably everything that depends on NewPipe). I updated mine yesterday and it looks like all video comments work again.
I have flickering issues with some Electron apps. Everything else seems to work fine, including a 2nd monitor. But I still dual-boot Windows for games, I'm waiting for HDR support to fully make the switch.
It's planned to be 100% API compatible with Lemmy, so you'd be able to use any Lemmy-UI with it. IDK why LW or any other instance would change their default UI.
A lot of things are not final and may change, but let's just start with their stated goals, instead of speculating about all the things that could theoretically happen.
What does their multi-device story look like? Can I use one identity/account on multiple devices, with synced read state etc?
Edit: Looks like it's being worked on. I don't want to use a messenger without this feature anymore, but I'll give SimpleX another look once it's done.
I don't think there is anything to be concerned about.
Sublinks will live alongside Lemmy, just like kbin does today. Some Lemmy instances might switch to it under the hood at some point, but as a user you probably woudn't even notice the change. All the data would be preserved, so your community would still be there unchanged.
It is basically Lemmy written in a different programming language, with more focus on moderation tools afaik. So for users it looks and works just like any other Lemmy instance does, and it's part of the same Threadi-/Fediverse.
The ad blocking on desktop doesn't really work very well in my experience (long loading times, shows ads anyway, ...). What has improved the experience for me tremendously is using an extension that automatically mutes ads.
Notion + OneNote/Samsung Notes
There is a myriad of open source notes apps, but none of them really hit the spot for me.
