If they do that I'll go back to writing about them after they ship. Not a big loss for me at all.
I get it, you would trust yourself if you said that, but it doesn't really matter whether you say that or not, what counts for your ongoing credibility if you will preface every future blog post with, whether you got special access, a special deal, sponsorship, or the fact that you didn't get any of those things.
You're a reviewer. This is how reviewers stay credible. If you don't disclose your relationship with the thing or company you're reviewing, I'm probably better off assuming you're paid.
And if your NDA says you can't write that in your preface, then logically, it is impossible to write a credible review in the first place.
I recently started doing that: https://simonwillison.net/about/#disclosures and https://simonwillison.net/tags/disclosures/
awesome, thanks a lot that's important but ... sorry I just checked those, and I do think it's better to do it on a per-article basis, because a lot of your audience (I'm guessing) comes from external links, not browsing your website
this is (or should be) a pretty standard thing to do on youtube review channels (that I would trust), and it's not a bad thing to remind people of, on every occasion, plus it can function as a type of "canary" in cases of particularly restrictive NDAs
And the wisest part is if he writes something they don't like, they can cut off that advanced access.
As is the longstanding tradition in games journalism, travel journalism, and suchlike.
