I couldn't agree more.

Past the energetic side (so to speak), they are inhibiting humans from healthy emancipation.

Much things can be done through contemplation, from philosophical explorations, revealing introspections that make you know yourself better, unexpected realisations between idioms that leat to invention and creation, etc. Contemplation is one of the cornerstones of living an examined life.

Social platforms, through various means (likes/approval/limited-text-space/followers) veer the attention to the exterior, "what will they think?", "what is the appproved behavior?", "what insults are popular these days", etc. More importantly, they focus the interactions in the field of immediacy where needs and compulsions prevail. That is the realm of anger not contemplation.

In essense, they are training people to behave like reactive animals; amoebas. Training them further from the introspective qualities that would emancipate them.
