I'm guessing the idea is that yes, it's disabled now, but if you really didn't want it, you remove it (except for AI, of course, which you can't). If you have it installed, why not keep it up to date, so when you decide you want it you have the latest version?

The solution would be not to bundle the plugins then

That's would mean homogenizing all jetbrains ides, as theyre all essentially the same program with a different set of bundled plugins, optimized for web, Jvm, c, Python etc

I wish they would. They have a billion products many of which are just slightly incoherent flavors of one another.

I was talking more in context of bundled plugins which can't be uninstalled.

Apparently (per other posts), it changes the app signature for some platforms and ‘breaks’ the install.

The article mentions that removing a bundled plugin would break the code signing. I suspect allowing you to not update a bundled plugin poses a similar problem, they probably have a single signature for the entire package including bundled plugins.
