Given how fucked up the recent generation in thousand little ways and addictions is, and I personally believe predatory 'social media' and overall resulting physical alienation are the largest culprit, these steps are good or at least well-intended. Those corporations are predatory, aimed at weakest and most defenseless (kids), ruining their future lives one bit at a time.
Sure, it should be mostly parents managing their kids well and giving them smart phones or consoles as late as possible in their development curve, but if something is so harmful, some regulation makes sense. 0 sympathies for meta-esque corporations, its us-vs-them due to their endless greed.
