I have a hardware-related question. I want to know whether and how Thunderbolt 3 connectivity can be added to my PC setup.
I've posted my question here (twice, first one perhaps had off-topic phrasing) but it keeps getting closed as off-topic. The private message says "Instead of asking what to buy, try asking how to find out what suits your needs." - but I'm not asking what to buy!
Flagging for moderator intervention and asking for explanation didn't help - flag got removed in seconds without further explanation.
I do know that questions asking for hardware recommendations are off-topic, but so are questions for software product recommendations. Yet I see questions such as this one not being flagged as off topic, even though the only answers it got are product recommendations (and since it's not standard Windows 10 functionality, no other type of answer is possible).
I think my question about hardware is relevant to more users (basically everyone who bought an MSI X99S SLI Plus and is interested in adding TB3 connectivity), so is there a specific reason why the rules for hardware recommendations are stricter than for software?
