I appreciate the idea, but this "Attention Strike" for a single day will have clearly insignificant impact on tech services. It's like expecting a 4 hours long national protest to do any damage on the economy. I already don't use social media at all most of the days.

For an impact to be present it should last at least for a month. Not so hard to put in place, there are lots of people already doing some form of absteinance on november for no reason, there is pride month, there is christmas month, just need to tell em to reduce/stop using social media for this month (eg. November)

It's by reducing their daily usage of social media for a month that people will understand they can keep this routine even out of that month, and thus reducing effectively their revenue for the companies.
