Honestly who cares. Liking and using an open source project has nothing to do with supporting the creators political beliefs. Separate the art from the artist and enjoy things. This miserable attitude is holding us all back from being better.
Many people care and should care. Of course if a piece of software (or any project/tool, really) gets a lot of usage, it’ll indirectly make its creators more powerful. I wouldn’t want to make a person more powerful if they support horrible causes (like in DHH’s case), especially if there are many alternative routes to choose from that are less questionable.
