Donate to the Wikipedia fund drive. The wikipedia is a wonderful achievement of the kind you thought couldn't happen anymore. An open collaborative society that hasn't splintered or fragmented. No mass exodus of 20000 contributors who would rather go start their own thing has happened (I do know that looked like it could happen at one point but at this point I think Wikipedia has established itself as the place for this kind of thing).

On the outskirts of the project the usual threats do exist: Tacky me-too operations whose only skill is search engine optimisation sometimes manage to make their pages of ripped-off Wikipedia content hide the actual Wikipedia. If this was loyal open mirrroring that would be great, but it's not - it's just another ad-serving platform. Old media people disregard the fact that a lot of smart people do most of their work connected to the internet, so they (the old media people) take it as self evident that an open system on that crazy internet can't possibly produce information of value. Finally, there is of course a problem with vandalism and partisan crackpotism - but the amazing thing is that none of this stuff matters.
