So despite assurances that "we will not sell, trade, or give away your e-mail address to anyone for any reason" they can change those terms "at any time without notice".

In case you missed it that time could be when 'selling, trading, or giving away your email address [or any data they have on you] for any reason [within the law in the jurisdiction of their choice]' and they wouldn't even need to make a note of that instantaneous alteration on their website. Of course they can, if they please, change the ToS right back afterwards the following nano-second so as not to put off new punters.

Now, I'm not saying they will but just that the power of that one line in the ToS obviates any assurances that the ToS give - it's basically worthless. All you've got is your trust of the current owner and all their associates.

Also it's worth noting that they could offer a with notice and acceptance [eg via a link click] alteration as, of course, they have your contact details. "But it's just a simple little notification site" someone might say, "they're never going to alter those terms to your detriment". In which case why not just promise to have you opt in again for any new ToS.

Storm in a tea-cup? Most likely.
