I've been using Nova launcher for just as long, and finally got off of it in November. First it was no updates, then whispers of ad injections, and now the ads are actually here.
With that said, I tried Lawnchair, and found it to be clunky, unintuitive, and either lacking the features that I wanted or I couldn't find them.
I ended up going with Smart Launcher, which has been a fantastic replacement. It's got everything that Nova Launcher has and more, and it's very easy to use.
If corporations are people, they should be able to be given the death sentance. I can think of a few that are directly responsible for the deaths of a lot of people, and all they had to do was pay some fines/lawsuits. DuPont comes to mind.
