Some statistics about all robotic #LunarLanding attempts so far from 1965 to 2025 compiled from https://en.wikipedia.org/wiki/List_of_missions_to_the_Moon and https://scicomm.xyz/@AkaSci@fosstodon.org/114636519291241321 in which I only count those for which descent to the surface had been initiated, not missions lost at launch or on the way - in a nutshell ~70% of all landings by government agencies went well (essentially the same rate 60 years ago and now!) but only ~30% by private companies. Here goes ...
There have been two separate periods of soft lunar landing attempts of ca. a dozen years each, from 1965 to 1976 and 2013 to 2025 (ongoing) with a huge gap between them.
In the first interval there were 20 attempts with 13 successes (Luna 9, 13, 16, 17, 19, 20, 21 and 24 and Surveyor 1, 3, 5, 6 and 7), one partial success (Luna 23, counting as 50%) and 6 failures (Luna 5, 7, 8, 15 and 18 and Surveyor 4), so the success rate was 13.5/20 = 68 %. All missions were by - the Soviet and U.S. - governments.
In the second interval there were so far 14 attempts with 6 full successes (Chang'e-3, 4, 5 and 6, Vikram 2 and Blue Ghost), three partial successes (SLIM, IM-1 and 2, counting as 75%, 50% and 25%, respectively) and 5 failures (Beresheet, Vikram 1, Hakuto-R 1 and 2 and Luna 25) so the success rate was 7.5 / 14 = 54%.
But looking only at the government missions it was 72%, slighly up from 50 years ago. While for the commercial attempts it was only 29%. In total the success rate was 19 (18 government-run) missions out of 34 (28) attempts or 62% but 69% for governments only. And if you throw in the 6 Apollo landings, the total success rate rises to 68% and the government-only rate goes even up to 75%.

The fediverse is often full of drama with admins falling out with each other and defederations, and threats and tears.
Now, with the public spat between the Twitter admin and the TruthSocial admin, the rest of the world gets to enjoy a similar spectacle!
They can't defederate of course, because Twitter never became open enough and TruthSocial was already defederated by everyone as soon as it existed.
Only on Fedi can you get the full experience of a public spat and defederation, because only on Fedi can the admins really at-mention and and directly reply and take the final dramatic action of a flouce-defederation.
Trump fans who are Twitter users can't port their followers over to TruthSocial, and Turther Musk fans can't just migrate their account to Twitter.
They're stuck.
So you see Fedi really is the best when it comes to massive public spats between admins and this current admin-drama is only getting more attention because it's between two of the worst people in the world.
