CRTs emit gamma ray at high power(>5kV is usually the quoted figure), and the standard solution was a bandaid fix of attaching leaded gamma ray blocking glass onto the screen. This high lead glass cannot be recycled, and the EU(rightfully) don't like any of that. I don't know if manufacturing of CRTs are banned or legally infeasible, but it's clearly not encouraged.
There are still some types of CRT-related vacuum tubes in production for applications digital equivalents are objectively less performant in.

Like what? The only significant applications I'm aware of for vacuum tubes nowadays are high-power RF amplifiers (including household microwave magnetrons) and intentional X-ray emitters.
