In theory I'm OK (kinda) with regulating the "overall design" somehow, but I don't see how it's going to work. Forced interoperability is a (very?) good idea, as it's really general, but it also doesn't address directly what the article and most comments talk about - the rage bait. I just can't imagine regulations (or "laws" or whatever the correct term is) that deal specifically with the algos that push rage bait that can't be later abused, if passed, to deal with other unpopular speech. And it seems like people want some laws to directly deal with that - the bad types of speech or algos themselves.
To clarify, I use "rage bait" as an example phrase, but it includes algos that only promote engagement at any cost and other things that aren't outright dangerous, but we think are dangerous. Not, like I said, CSAM or yelling FIRE or telling people to kill themselves.
Interoperability sidesteps the issue by giving users the choice of which algorithm (or algorithm provider) to use. The majority might or might not agree with that approach - for example obviously tobacco has not been left purely to the individual's judgment in the west.
Agreed, you can't regulate speech in a targeted manner while also not doing so. You're forced to find some common aspect much more general than "rage bait". Perhaps prohibiting the targeting of certain metrics? Or even prohibiting their collection in the first place.
