If you use a reputable adblocker, especially a well known FOSS one like uBlock Origin, you’re not the product. The way they block ads is by downloading static filter lists, not live checking by sending your queries to their servers.
I’m not saying all adblockers won’t track you, but acting as if people are “Adblock’s product” by using adblockers is simply a misinformed view of how most adblockers operate. (I do agree that marketing adblock as a solution for a legitimate issue doesn’t negate the initial problem or its critics, though.)
I haven’t had a single issue with crashes, noise, heat, display, etc.
The positioning/gaps of the spacers are extremely tiny, and barely noticeable, and the only issue I’ve had so far has been my laptop not turning off fully when I shut it down, but that’s fixed by just holding down the power button.
Oh, and I’m running an unsupported linux distro, (NixOS) so it’s not like I’m starting from any advantaged position in terms of software integration.
Performance is great, cooling is great, games run well and it boots up quickly. Nothing much else to say other than it’s a good laptop.
