this is just how trademark works, and it's mostly okay. it also sounds dumb that park tool can trademark the color blue, or kubota can trademark the color orange.
but park tool's trademark is only in the context of bicycle repair tools, and kubota's is only for tractors. the law just isn't that dumb, it's interpreted by courts and real people, who are capable of saying "no, that's dumb" if something is dumb. kubota can keep their trademark, and everybody else can keep making orange things as long as those things aren't tractors or tractor-like things that are going to get confused with kubota products.
similarly, any somewhat reasonable person will be able to see that twitter's rebrand to "X" isn't really going to confuse anybody into thinking they're using a microsoft product, so depite it being a very bad name it's probably not actually going to run afoul of anybody's trademarks.

I feel that reasonable people and the people who suffer from Musk Derangement Syndrome (seemingly a lot of the people here...) are two very different groups.
