Going would be good.
I know people are meme'ing about you getting tar'd and feather'd by companies who's products didn't do so well (but I think this is an overestimation of them actually caring to that degree).
Also, I don't understand what there would be to feel uncomfortable about. The value system on this planet is flat out retarded. Why would I get mad as a company for someone who revealed the flaws in my product? Sane, rational people would pat you on the back out of thankfullness so they know what to look out for in their next iteration. Only the scum/criminals out there feel like you're screwing them over with analyzers spitting out measurements, I'd feel even more compelled to go if this was indeed what some companies would feel about you, knowing you're on the right side of things you can then face them with a -straight face- while they.. not so much.
It's not like your reviews are out of their control.. you barely even do reviews in the pervading and colloquial sense (reviews where a subjective take is 90% of the ordeal), you give your take on the testing you perform and explain to folks why its relevant and in what way. The times when you open a unit up and reveal things to be unsatisfactory also isn't something you are in control of (revealing things like idiotic heatsink design/positions, and wiring gone haywire). SO, if they are upset about getting a bad "review", then they should just make a better product that isn't plagued with blatantly purposeful design flaws due to self-imposed ignorance.
Don't ever feel uncomfortable for what you do unless someone is literally out to cause you direct harm. If there are companies that don't agree with what you do.. GOOD, we then know who to avoid like the plague - as those folks are uninterested in the betterment of the industry of audio. You will always have some folks who will stand behind you when you do the right thing.
