I must have taken some shrooms before I downgraded from Tahoe to Sequoia a few hours ago then.

Old Macs can certainly be downgraded. iOS doesn’t allow it though and they pulled the latest security update which fucking sucks. And if you buy a M5, Tahoe is the only OS that’s available.

Oh, I must be clear here: I'm not considering M1 Macs or later, since Apple closed the ecosystem with Apple Silicon.
What you did is a downgrade in what's called the supported OS.
However, if you decide to downgrade to Catalina on an M1 Mac, it's not possible — Big Sur is the earliest version that runs on Apple Silicon.
Anyway, you cannot downgrade to a macOS version older than what your Mac originally came with. So if you buy a Mac now, Tahoe will be the minimum option.
