A little embarrassed to admit that I had forgotten about @Vivaldi
They actually allow donations now. So I'm going to take Vivaldi for a more serious spin for a few months and also setup, during this time, a recurring monthly donation. And I guess I have to eat my own words and pay $50.
I discovered this because of a Toot from @jon and having read through much of what's on Vivaldi homepage... we have somewhat aligned incentives and "values".
Let's do this!
