Good point, and we should probably tease apart that distinction between funding models and project intent/scope. For me, I've always seen apps like Boost, Sync, Infinity, and Jerboa as being "indie passion projects" regardless of how they pay their devs because of things like the project's scope, the dev team size, and their community involvement. They just don't strike me as the kind of apps you build for their "explosive growth and profit potential," you know? So by extension, I've got to assume anyone who builds one is doing it because they love lemmy, wish it was better, and happen to have a little coding knowledge to do something about it. That's a mission I can get behind.
Funding, on the other hand, is something that everyone needs but no one has actually figured out. So as long as it looks like a dev is experimenting with their options in good faith and honestly engaging with the community to figure out what's best, I can't really fault them for going with one model over another. I've got my own preference for open-source community-funded projects of course, but I'm not going to begrudge a dev for seeing it differently.
With Boost, there's an ad-free and privacy-respecting option, and then there's an Admob version. Those are the two most common funding methods out there, and I'm not surprised in the slightest by any dev who reaches for them as off-the-shelf answers. Lemmy has an open-source vibe, sure, but Boost started as a reddit app. Go with what you know. I might be wrong, but it doesn't feel like the ad supported one is being built to harvest data - it's just a drop-in advertising space like websites have used since the beginning of time. And if I'm really that concerned about it, I can pay for ad-free. Do I wish that it was open-source, patreon supported, and community built? Sure. But this ticks enough of my boxes to say "sure, why not," and then casually watch how the conversation about funding plays out in the comments. Who knows, maybe the dev will open things up or add a donation-ware version based on feedback, and I can upvote the Lemmings who suggest it.
I guess what I'm trying to say is that the project feels genuine and in a spirit that I can support. The foundation is solid. Everything else is just details, and I'll happily tag along for the ride as the developer, the community, and Lemmy as a platform figure out what that means.
There are a lot of comments here about which launchers are "close enough" to the Nova feature set, but very few people are talking about specific features and the alternatives that support them. I really just use two, and everything else is a cherry on top that I can do without if push comes to shove.
Action Launcher used to be my go-to, and it's still the best implementation of #1 because of the little indicators it adds to let you know if something is a "cover" (folder when you swipe) or "shutter" (widget when you swipe). Sadly it's gotten rather bloated over the years and spends more time force-closing from one glitch or another than it does actually running properly. Nova was my backup because it added "covers" a few years ago and I remembered enjoying the app about a decade ago. Now what?
