Trademark law is ridiculously slanted in favour of existing rightsholders. The most famous example I know of is "McSleep Inn", which was sued by McDonalds and forced to change their name. I think that ruling was complete bullshit, because Mc is so generic and usually a prime factor of trademark law is whether the businesses operate in similar domains, but it goes to show how broad the protections can be. Something like "GitFoo", which is explicitly being used specifically on a site for hosting Git repositories, doesn't stand a chance in hell, and rightfully so because this is actually trying to take advantage of Git's name to market their product.

They might have been sued, but did they change the name just to settle out of court? McDonald’s failed to maintain the trademark on “Big Mac” in Europe when it actually went to a court room https://www.theguardian.com/business/article/2024/jun/05/big...

		They did not settle, hence my usage of the wording "ruling" and "forced to change". > For the reasons given the Court finds and concludes that (1) McDonald's is entitled to enforce its family of marks that are characterized by the combination of the prefix "Mc" with a generic word; (2) the name McSleep Inn is likely to cause an appreciable number of the public to be confused by believing that McSleep Inn is sponsored, associated, affiliated, connected, or endorsed by McDonald's; and (3) the adoption and use by Quality International of the name McSleep Inn was a deliberate attempt to benefit by the good will and reputation of McDonald's. Therefore, the Court will find trademark infringement, unfair competition, and dilution under the Illinois statute (Ill.Rev.Stat. Ch. 140, § 22). https://law.justia.com/cases/federal/district-courts/FSupp/6... I suppose it's not surprising that Europe is less favorable to frivolous trademark claims made by American corporations than America is.
