I think it’s really hard to balance without giving us better personal search settings. This is anecdotal of course, but I rarely find anything on free “as in beer” media that’s worth my time. If Google excluded paywalled content its search functionality would be a lot less useful to me as a result.
On the other hand, you don’t subscribe to everything, and it might be useful to tune some of it out. Like I have a subscription to two Danish news papers, Information and Weekendavisen, and I like when google provides me with articles for them, because those articles are often going to be the height of what I want from my search results on subjects they cover. I don’t have a subscription to other Danish news papers, however, and maybe google would be better if it let me filter them. Maybe not though, it would certainly increase my personal bubble, but banning paywalls outright would really break google for me.
