Yes, it’s not a great security practice, and it probably should work more like "we’ve noticed you have randomly changed your search engine from google/ddg/bing/whatever to this ‘random search engine no-one heard about’’ instead of blindly reverting to edge and bing.

It seems to be a tool for tech illiterates. A power user will know how to avoid malware, and remove it if they catch it.

They should do a much better job than that, but helping people that don’t know what they’re doing is not itself a bad thing.

Ehh, time to play a bit of a devil’s advocate.

“Bing with Edge”,

1. it’s talking about search engine in edge
2. a lot of malware will change your search engine, so that may make sense, for less knowledgeable people
3. it won’t do anything on its own, you need to accept the repair step, for your default browser and/or search engine in edge to change

But systemd is not a single tool, nor a single binary, it’s a collection of tools.
