It is genuinely very confusing that a mental health problem has turned into tech regulation. Particularly when mental health treatment is so obviously lacking (and part of the reason why no-one asks the question about the NHS is due to lobbying, the NHS has the most powerful lobbying group in British politics).
Btw, just anecdotally, the people pushing for this are (imo) the worst people in British politics. Bill Cash, all the Brexit hardliners (who, btw, were regarded as too incompetent and mad by the people who can the Vote Leave campaign). These people sit in safe seats, there is no risk from deselection, and they just sit there and come up mad ideas year after year (the person above who points out that British politicians tend towards authoritarianism are correct...this is being led by the furthest right portion of the Tories).
