Oh yeah for sure lol. Don't know how I could miss that since one part of the NDA shenanigans with the particular company I was talking about was that another company bought it during the same period that I started there and a lot of things changed essentially overnight (at least according to colleagues who had worked there for a long time).
The full story is ridiculous / hilarious:
The acquisition meant that between the period that I got the official contract (which was supposed to be the new parent companies contract but their HR department refused to send it out to the then daughter company, so I ended up with the old default contract for the daughter company) and signed the contract, and when I started working (which was a couple of months due to reasons) they had an updated "NDA" which actually was a new employment contract with a lot more terms than were in the original contract (and that were illegal in my country, at least according to my legal counsel).
So my first day at that place a new "NDA" waited for me on my desk which turned out to actually be an employment contract. And apart from it having illegal provisions in it, there were references to me accepting an NDA rider that was not available to me at that point so I asked for a copy of that.
In the actual NDA there were even worse provisions. One clause in the contract expanded (it wasn't explicit but that was what it meant) to me not being able to get a mortgage (or even a bank account) in my country (because I would not be allowed to do any kind of "business" with any company who was a customer of my company, or that was a customer of our customer due to them using our software (and we provided FX software for banks).
Another clause explicitly said that all intellectual property that I produced from the time that I signed the NDA were properties of the company, and they would own all intellectual property that I produced UNTIL THE DAY I DIED (including after leaving the company), so after leaving that company I would not be able to work at any place that would expect me to provide intellectual property for them (unless I fought that admittedly illegal agreement in court).
Obviously I refused to sign the new contract and sent an email to the daughter company CEO (we were less than 40 employees) asking to set up a meeting. I then never got a reply until ~6 months later when I was threatening to leave (partly because of this, partly because of payment disagreements, partly because ~25 employees of the daughter company had resigned and left from when I started to that point). Then he really apologized and admitted in a private meeting that no, the employment contract was not enforceable in our country and that even presenting it to employees as something that they might be asked to sign would be grounds for sanctions for the company. And then he managed to convince the parent company to get me a counter offer to get me to not leave which was super insulting (~50USD/month raise), combined with trying to get me to take over as head of operations for the daughter company (because, apart from me and one other person the whole ops department there had resigned).
So obviously I left. And after I resigned the parent company refused to pay out overtime because "there is no explicit agreement with the /new/ company about overtime compensation", and they did some other things to try to screw me over.
There are also some hilarious stories about the guy who stayed and what they promised and how they "fulfilled" those commitments. But that's not my story to tell.
Anyway sorry for ranting, apparently I still have some sore spots regarding this company lol.
And tl;dr: just because your company might be cool right now and you trust it, it might get bought up tomorrow and everything changes overnight.
edit: I got around the "requirement" for me to sign the new contract / nda by getting an email from the local HR asking for me to send in the NDA and me responding with a PDF of the signed origal contract and an email saying "here is the contract that I have signed", and then it freaked out the parent companies HR person during the exit interview when they looked me up in the system (because they had a history of making a point of saying that their intention was to enforce the NDA + employment contract as harshly as possible) and I then told her to check the related PDF.
