Why would you buy one when there are so many alternatives?
So if for example inserting a more trusted PCI nic card, and just ignoring the 
intel nic, it should be no problem?
Not how it works, intel nic or not you have the same level of security once you use me_cleaner - additionally the non LOM series intel nic ASIC's lack the ME ability irregardless and one can also modify the LOM series firmware to remove that ability.

The whole "oh you are fine from hypothetical nation state backdoors if you use a non-intel nic" rumor was started by purism - it is absolutely false. If such a backdoor existed they surely would have thought of that already - there are a variety of methods to communicate and control with a PCI-e networking device without having drivers for each and every NIC on the market.
