I’m asking this because one time, while browsing the GNU website, I noticed that some of the members’ emails had “gmail” on them!! And I asked myself how would that be possible?? And I think other members of the FSF had Gmail too. Why? Richard Stallman is against Gmail, so why would those memberse use it?? Would that mean I can use non-free software while advocating and loving free/libre software??
I mean, it’s not like slavery or murder.
Being pro-FOSS does not mean you are anti proprietary software. There’s plenty of middle ground.
Video games, for example, where the company might not want to open source their server code for plenty of very legitimate reasons.
Mail is a super important utility. For physical mail, it’s a felony for anybody to open it. For digital mail, gmail open, reads, and inserts ads before handing it to you. It’s ok to think some things are important enough to mandate FOSS, and some things not.
