I am not sure whether the wikimedia foundation actually needs money from individuals. From what I could find by searching “Does Wikipedia need donations”, they seem to have plenty of money. I’ve also seen from people that after donating, they like to haunt your email inbox for more money.
I myself prefer donating elsewhere instead. In my opinion a good alternative is archive.org. It’s hard to track how much they get sued, and now they even were hacked recently.
Well, just another kind of non-traditional relationship. If it’s consensual between all 3 of them, then how I feel about it doesn’t matter. It may be a harmful relationship indeed, but it also may not. Just like any other relationship.
But, the more you show her that you are not okay about her being in such a relationship, the less she’ll tell you in such case. Plus it is also harmful on its own.
