Look, I get where you're coming from, but there's a difference between a $965B corporation whose sole purpose is to harvest your personal info for ads, and a solo dev who just wants to make their (and your) Lemmy browsing a bit less painful. They're putting in a hellofa lot of time and effort into this thing, which means a hellofa lot of time not spent making money at a regular job. I'm more than happy to kick a few bucks here and there to keep something like that afloat, especially given how apps like Boost and Sync make me actually want to spend time on Lemmy. Encouraging fediverse adoption is a win for the whole ecosystem. You don't have to use Boost, and if you do choose to install it, you don't have to pay. There's an inexpensive ad-free version alongside the ad-supported one for exactly that reason. But complaining about Boost because you hate "social media apps" is like yelling "Fuck Nestle" at the 12-year-old selling lemonade from their driveway. Different scale, different purpose.
It's fine to not pay, but I'm glad that some people do support indie devs when they can. The world would be a lot bleaker without little passion projects like this dotting the landscape and filling in the gaps to help bigger projects like Lemmy take off.
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?
