I read the Wikipedia article about "gaslighting" and know it comes from a 1944 film of the same name in which an abusive husband gradually dims the gaslights at home – while denying doing so – to drive his wife mad.

Yet whenever I see the term used (which happens a lot, lately) I can't make the connection. It seems people use it for the simple act of lying or denying something, which to me is mostly just... lying, not "gaslighting". Any kind of stupid, misguided act is getting the sinister "gaslighting" stamp as if it some 5d chess move when it simply looks like incompetence. The core principle of it seems to revolve around having a plan to psychologically manipulate someone but I mostly don't see the plan nor the actual goal. If anything untruthful you say about an important topic is "gaslighting", then the term doesn't seem to have a lot of value on its own. Wikipedia actually mentions "unconscious" gaslighting which seems to contradict its purpose of actually wanting to manipulate someone.

So, given its popularity, I'm curious if there might be a (succinct) definition of the term that helps me understand it properly? Do you think it's just a trendy term to throw at politicians doing shit you don't like? Am I missing an important detail?

With the ever-growing stream of acquisitions and mergers, it got me thinking: Why do we permit companies to do this?

What would the harm be in banning this practice? If a company is becomes insolvent, release all of it's IP to the public domain, dissolve all patents/trademarks, and sell off physical assets to pay debtors (first of which should be former employees IMO, but that's a separate discussion).

Edit: I think my original intention of the post to kick off some interesting discussion has worked. Thank you to all current and future posters!
