The civil lawsuit by individual victims won't be effective. If it does, Alphabet and other US-based tech companies should have been behaved better decades ago. For them, this civil case means nothing. Think about it. Are you and all the people you know going to boycott Alphabet just for this particular civil case? No way.
The better solution is make a regulation which makes Alphabet and its boards criminal if they ignored it. But it looks like defamation isn't more important than copyright infringement in US.
I didn't say anything about boycotting - I suggested that repeated lawsuits like this one will force a change. Regulation is absolutely the ideal way forward but the US is horrible about effective regulation so the legal system is probably the most practical enforcement method we have.
I agree with you, regulation would be better. But much like the alcohol and tobacco industries tech corporations spend millions in funds on lobbying US lawmakers to avoid being forced to accept government regulation. Also my case actually has done some good. Someone contacted me to say because of it her lawyers were able to get content malicious content removed posted by an ex partner. Over the years I have been contacted by quite a few people who have said the same thing.
