> There is also Ladybird, whose founder is a prolific and technically brilliant person but who is also, at minimum, a fascist sympathizer, in addition to being a supporter of white replacement theory and other racist ideas.

I know nothing about Ladybird or their founder, so I'm taking your word for it that they are "at minimum, a fascist sympathizer, in addition to being a supporter of white replacement theory and other racist ideas."

Accepting the premise, this leads to an interesting philosophical discussion. I'm utterly repulsed by all those things, but I'm also repulsed by viewpoints and even personalities of some actors and musicians and such. In my younger days I couldn't even enjoy their art. There would be songs or shows I loved but couldn't listen to or watch once I knew about the musicians/actors views. However as I've gotten older, I've gotten more to a place where I'm able to separate the art from the artist and appreciate it more (still not perfectly, but I hope to get there someday).

I'm now asking myself if I could use and/or support a browser like Ladybird (assuming it's a good product, again I know nothing about it) even despite the founder's reprehensible views. I'm not sure, but I feel like I want to be able to.
