Big Tech companies decided to crack down on right-wing mobs set on overthrowing the US government (or worse) just after they learned that Democrats would control the Senate. It could be a scheme to convince them not to break up those Big Tech companies.

I would guess that Big Tech is also working on acquiring a few Democratic senators to block anything that might reduce their power.

Is DNA engineering anything like programming? Can we reach any ethical conclusions about its "source code"?

Look at the workings of a Covid-19 RNA vaccine.

That RNA is not compiled from "source code"; there is no such technology. I don't think it is much like programming, either; this looks to me like a field of physical engineering. So I don't think we should try to understand it based on software. We should think about it independently, based on our general principles; some of the principles we apply to software may be pertinent here, but they won't lead to the same conclusions.

Glenn Greenwald notes that when three Big Tech quasimonopolies shut down Parler, they demonstrated that they have considerable censorship power over society.

He also says that, counter to widespread impressions, Parler did not intentionally promote any particular political current, did not permit advocacy of violence, and was not the main way insurrectionists communicated to prepare for insurrection.

*If these firms are so powerful that they can be the primary gatekeepers between a president and the public, then they have outgrown democratic control.*

(satire) *Citigroup Begrudgingly Keeps Funding Marco Rubio After Learning Senator Voted For Election Certification.*

There are indications that some Republicans in Congress aided the insurrection, including helping participants plan in advance how to attack the Capitol.
