I understand it may be difficult to close your accounts on these dumb social networks but you can use a browser like Brave on your mobile and access them through the browser. You'll find your phone runs better without the apps installed on them.
The benefit of doing this will mean you have less chance of being counted as a monthly active user (MAU) in their reports which will help put more pressure on them.
