It does, actually.

Monobook was already no longer supported and on the chopping block for some time. It did not suit the purpose of modern web design and browsing.

Adding the necessary updates to its heavily forked MediaWiki in addition to Oasis, Mercury and Discussions would increase the workload substantially and force them to run different trackers parallel. They could allocate neither manpower nor time to restart support for Monobook for this update, and then support it for some time to ensure continued compliance with GDPR.

It's a cold business decision: as Monobook has no ads and provides little to no income, sinking more money into it wasn't justifiable financially. Better to sunset it now than invest in something that's past its expiration date.

That's the gist of it. It sucks if you're used to it, but Oasis has been here for 8-ish years and has undergone extensive improvements since the early version. It takes a bit of time getting used to things, but the editing is pretty much the same.
