I give 5€ per year to Wikipedia

[Gribouillis]

f they want money, they should support advertisements - there's literally no better place for a privacy-respectful non-intrusive targeted advertisement for something relevant than on a page about the topic (most of which are written by experts, many of whom could do with the support of being able to better market their awesomeness, directly to people who almost certainly need their help).

This is so absurd! Why should they support advertisements? To please you? Advertisements are anything but «privacy respectful» or «non intrusive», they are the ubiquitous PLAGUE of internet. They are imposed on us defenseless users of internet services.

If they allow advertisements, I will stop using their site immediately.
