For storage, for free options I'd recommend filen.io, which gives you 10GB free. If you're open to other paid options, proton drive and infomaniak drive seem alright.
Just skimming the alternativeto entries for google photos, the open source alternatives to Google photos look like they tend to be either paid or self hosted. Stingle Photos has a free 1GB tier you could try out. Otherwise, paid options include Stingle, ente, and seafile, and self hosted options include immich and Nextcloud (which is also a drive alternative).
I think its also important to note, he was not explicitly unclear about what Firefox was, he was unclear about what Mozilla was. It's admittedly still not great, but I think it's a little more understandable a thing to be unfamiliar with than the browser itself. I'd really rather the title referred to Mozilla because of this, as really there's little to definitively back up its claim that the judge is unfamiliar with Firefox, just that he is to some degree unfamiliar with the company that makes it. Again, still far from ideal, but not nearly as egregious as they're trying to make it sound.
