I think it's the same reason teenagers in the US don't want to be seen with Android phones. MariaDB is not fashionable or high status. People think they are making all these decisions on a rationale basis. But humans, including software engineers, are herd animals. The drive to conform will push humans to do all sorts of irrational things. I still use vim (neovim) despite decades of hating certain things about it. I think also that many developer's only real way of judging engineering is whether it conforms to certain stack or process patterns that they have heard of. Use the wrong stack or leave out some process and in their eyes you must not be a serious engineer. They aren't capable of or interested in looking into the details of the requirements and execution to judge you.
