Interesting piece. Definitely worth a reading the whole thing, but here is Bing AI's summary:
Reddit’s decline: The author argues that Reddit is becoming less relevant and more generic as it tries to squeeze its users and moderators for profit. He compares Reddit to a dying mall that is losing its cultural middle class to decentralized platforms.
Enshittification: The author explains the concept of enshittification, which is how platforms attract and then exploit their users and businesses. He gives examples of how Facebook, Amazon, Twitter, and Google have followed this pattern.
Moderators’ resistance: The author describes how Reddit’s volunteer moderators are obstructing and sabotaging Reddit’s attempts to enshittify the platform. He says that moderators are the ones who create and curate the content that attracts users, and that Reddit is losing their trust and cooperation.
Fediverse’s rise: The author predicts that Reddit’s users and moderators will eventually migrate to the Fediverse, which is a network of independent and interoperable social media sites. He says that the Fediverse offers more freedom, authenticity, and sanity for online discussions.
I'll give you a little more nuance than the previous reply. The intended purpose of hearings like this is as a prelude to legislating. A congressional committee brings in experts of various sorts so that representatives can ask questions and gather information. From there, they would presumably go about crafting legislation to address a problem. It is true that in modern times these hearings have mostly devolved into theater, a way for representatives to haul someone into a public setting and yell at them to score political points, or to draw attention to a particular pet issue. Legislation still often follows, but the legislation is more likely to be theater itself, what are referred to as "messaging bills." Representative X gets to tell their constituents that they care about an issue, brought those responsible in front of congress and gave them a piece of the reps mind, and then proposed legislation to tackle the issue, but it was held up by the other party, but you should vote for me because I am taking action on this issue you care about.
It is also worth mentioning that Congress also has an "oversight" function to serve as a "check" on the other branches of government, the executive and judiciary. In that capacity, Congress can get records and demand testimony from the executive branch (they usually don't go after the judiciary) about things the executive is doing, mostly to draw attention to bad behavior to put pressure on the executive to change, though Congress does have some tools like legislation and particularly budget controls they can use force executive policy changes.
This particular hearing was in front of the House Oversight Committee, so the "purpose" was to conduct oversight of the military and CIA over their handling of UFOs or whatever. One of the questions the "whistleblower" was asked was about how this secret alien tech reverse engineering program was funded - Congress sets and controls all of the federal agency budgets, so in what way has the military or CIA or whoever been able to move money Congress appropriated around such that they could fund this super secret program? Of course, our "whistleblower" totally knows the answer to this but just can't actually say right now for "reasons." Presumably, if Congress cared and actually believed this shit, they could include language in the budget bills to close whatever loophole exists and/or require the Pentagon or CIA or whoever to disclose information about this program.
But watch them do nothing, because this was probably more of a stunt to rile up the conspiracy minded than it was anything substantive.
