Sometimes, I feel a strong desire to pay for brilliant software, but if a free option exists, I often end up using it—even though I benefit greatly from these tools. But I support those software providers express their values, or encouraging more people to join the cause of freedom,or charge, or just add some ads.
I’d rather chip a couple of bucks to Servo instead, which funnily enough, actually used to be under the Mozilla banner but a round of layoffs ended up cutting the team working on it. It’s development recently picked back up and there’s a small team working on it (I believe from Igalia) again this time under the Linux Foundation.
