I also second the first post here. There are moe areas where it applies, e.g.:
- the use of Google Analytics on many, many websites. Beside that it is of course a Google tracking service, which – not surprisingly – makes many people upset (even so that some abandon Firefox), but it generaly also, of course, is proprietary JavaScript.
- Auth0, used to signin to this forum and as it seems also for Mozilla internal services, is yet another proprietary service. After Mozilla abandoned it’s own service for that (Persona), they now depend on a proprietary service, which could always go down, which might really hurt their own internal services. Besides the fact that Auth0 get’s the power of authenticating Mozilla employees, tracking them and do other evil stuff. Also, it has other downsides as well.
Just so you see: It has not have to be this way. This forum itself, BTW, is a really nice FLOSS software. Discourse is completely open-source, so yeah! It works.
