I thought the issue was that it comes installed by default. Like the old “Microsoft installed a browser to kill netscape” brawl in America.
I just don’t get the EU’s overzealous regulations. Who is being hurt by Teams? Slack/Discord/Zoom? I doubt any major companies are using Teams just because it’s installed. They may be using it because it’s part of the Office Suite, but shouldn’t they be allowed to bundle that? Should Adobe not be able to bundle everything in Creative Cloud? It just seems so arbitrary.
These are questions for the democratically controlled regulatory process to decide, which is what's happening with Teams.
If you feel that Paint should be considered a harmful bundling practise under current laws, you can organise and push for that investigation to happen.
Will it be difficult? Yes. These institutions are slow moving as society is vast and complex. Is it worth it? Yes. Democratic institutions and regulations are the best way we've discovered to conduct human affairs at scale.
Which is hilarious considering that zoom took off without bundling with anything - while slack STILL is unable to offer a proper video conferencing.
