what’s novel is the centralized nature of social media (in terms of # of people reached from a single source) and the fact that some incredibly wealthy companies control these sources and face an existential risk if their platforms are used to create enough civil unrest that whoever ends up controlling the government is convinced that these companies are too dangerous to leave unregulated.
Many, in fact, were not, even if some participation in the practice at the time. Look at the pushing of anti-Western intellectualism and rejection of the basic tools of logical reasoning, which trace their roots far back to the Ancient Greeks, for being the "Master's Tools" to ensure supremacy.
At the end of every disagreement is violence as the final method of conflict resolution. That these ideas are pushed, is just another log on the fire. Part of classical logic and rhetoric was teaching the ability to utilize them to defuse and avoid violent resolution of disagreement through reference to an objective or common reality.
You may not think the above poster has a point, but they most certainly do.
But their leap to "if X is banned and Y is similar to X and Y isn't banned then X can't be banned" is still wrong because it is not the similarities between X and Y that is causing X to be banned.
It is the fact that X is being used to inspire violent opposition to the government that is the source of the banning.
Or to make it much less abstract:
A bunch of people broke into one of the most important buildings in the US government, killed a police officer and wounded others who were trying to stop them, stole stuff including computers belong to high ranking government officials, broke stuff, humiliated the government, and had every appearance of being willing to cause physical harm to political leaders because of X.
X was supported by social media.
Social media hosts reasonably concluded that the government may cause them to suffer negative consequences if they did not do something to prevent this from happening again.
Because of Y, some people have gotten into fights on the internet and a few individuals have found their employment and social options constrained. The government is not nearly as interested in this.
why it is being banned is that it has convinced people to attack the government because they believe the government has done things (for example, “stealing elections”) that it has not done.
big tech has apparently decided that they do not want to be blamed when the government has to shoot a bunch of delusional people to stop them from committing violent crimes based on lies
