Banning anti-competitive behavior (which is what antitrust laws are for in the first place). For instance: a company actively blocking competition (e.g. coffee machine manufacturers that make it impossible for people to buy pods from another brand).
Again, I am probably biased here, but I don't see much anti-competitive behaviour in the search engine space. If people have a clear superior alternative to Google, then by all means please share it here.
Even during the brief period where I used duckduckgo, I was constantly finding myself typing "!g" to get results from Google as they were just consistently more relevant.
What outcome are you hoping for here? Google can't pay to be the default search engine on a browser, no one can pay to be the default search engine on a browser, no one can be the default search engine on a browser, or just Google can't be the default search engine on a browser?
1 and 2. Google as the overwhelmingly dominant player should not be allowed to pay to further monopolize the space, and since Microsoft is the alternative, I would support banning paid defaults in general.
