Past experiences include Cisco (bad incentives, they make a lot of money from certifications and licenses), TP-Link (broke the case physically when pressing a button, was left without updates after some time), Ubiquiti (could not handle the load of my home network. I had the edgerouter-x though which is weak)
Why I don't trust any of them? I am not explaining this to a five year old as they will have endless questions. We would be here all day. I would instead give them some nearly pure sugar sweets and let them play on a game console and let their parents deal with the fallout. No idea if Pixie Stix are still a thing but that would be my "go to" if someone expects me to deal with their brat. They won't try that a second time.
In summary however they are all consumer devices have a low margin meaning to me that a foreign vendor would likely be easier to pay a nice lump sum to do anything from look the other way to utilizing a third party customized image that I provide them over Tor. The number of people with sensitive data would make the risk vs reward ratios desirable. There are higher probabilities that the generic devices would be utilized by members of governments, inner circles of corporations, secret organizations and so on...
A generic device meant for a small company is less likely to have world changing sensitive data and the cost is high enough that not many individuals or companies would make it a viable target. Cost vs. benefit vs risk vs reward... The vendor I am currently using at the moment is in the USA and I know they without hesitation would contact the FBI within minutes after writing a report with everything they know about me if I tried any shenanigans whereas vendors in Asia will not likely consider ethics of targeting those in the USA or the EU/UK and would happily take the money.
