I’d 100% donate to them if they accepted donations.
If they accepted donations, you wouldn’t want to.
The reason uBlock Origins surpasses all the others is because of who the lead dev is, what they believe, and why they do it. They are absolute hardline and believe in what they made. It’s not a job.
You don’t need to be that kind of person to be a good developer, but when it comes to something like an adblocker and privacy protection, you want people like him who won’t falter or sell out. You want those true believers.
If he accepted donations, then he wouldn’t be the kind of person that made uBlock Origins what it is.
