I used the first two, but just enjoy the experience of sync better. If sync didn't exist, I'd be just fine and happy still. But I currently browse Lemmy 30 minutes to an hour each day, so $20 for no ads is something I'll probably eventually pay for the hundreds of hours I'll use the app.
This isn't unusual for Enterprise grade IT hardware. Mainframes have been sold/licensed that way for decades. I recently dealt with a performance issue that we solved by buying a license to use more of a piece of hardware that was already in our data center (we didn't realize the piece we owned had twice the capacity that could be unlocked just through licensing till we engaged the vendor)
