Ich habe das zum ersten Mal auf Wikipedia gesehen

This advertisement is also misleading. Most people think they donate here to keep Wikipedia alive. However the wikimedia foundation behind wikipedia has already collected enough donations over the last few years to keep wikipedia running for multiple decades (!) to come. Therefore, these donations primarily go into other projects.

Wikipedia is extremely greedy. They already have more than enough money.

The beauty of open source is that you can download and self host Wikipedia on your own computer, it’s even <1 TB. If something happens to it, it will be rehosted within hours (possibly by some malicious parties, but that’s why you need a local copy).
