The software is free, but it looks like the trademark is not. So WordPress bans WP engine from some WordPress stuff b/c they aren’t technically WordPress. In other words, they’re free to use (and change) the software, but they can’t (or, rather, shouldn’t) use the name—according to WordPress. WP sues for usage anyway after they are barred from some event or something, but now WordPress is suing back, turning an unofficial dispute to a legal one.
It’s pretty. By default, even. Floorp is customizable, but many (most) people want a tool that works directly out of the box, and if it looks good while doing it, then it will be more popular.
The dev advertised it on Reddit, then when people complained about issues, you would see a response from them along the lines of “fixed,” which showed responsiveness, and I think that gained loyalty before the product was ready to be released.
