They used to make these beta versions private so only ios/macos developers could test on them to report bugs to get them fixed before public release. They since opened it up to anyone who wants to install it which generates a lot of outrage from the peanut gallery when the beta has bugs.
I think the reason so many people hit this in particular is enabling Sequoia beta channel is the only way to prevent the machine from wanting to upgrade to a newer major release.
