I've used Nova Launcher for years (don't know if I'm paid), but I'll be happy to pay for an ad free version.

I know there is a long history of companies buying another company for a product and then killing it after a period of time. I'm willing to give Instabridge the benefit of doubt... for a while. If they do decide that Nova Launcher is not a fit, I hope they open source it so that current users are not left on the lurch.
