That'd be anticompetitive and would be used against them in lawsuits. By Epic, who use anticompetitive exclusivity agreements & subsidise giveaways, but aren't in a dominant market position so it's totally not hypocritical.

People always point to email as a decentralized system that works. They forget that originally nearly everyone got email through their ISP, and now nearly everyone gets their email through their OS vendor (Google, Apple, or Microsoft), or for businesses one of the few commercial mass mail services like mailchimp that don't get blocked by spam filters. Self-hosting email is likely to result in a major hassle with undelivered emails due to anti-spam measures these days.
Blue lights suck. Yellow lights suck. White lights (6000K full-spectrum) are good, but more expensive and harder to find.
You wouldn't write a letter that's just "Hi " and then no body. You'd have the greeting, the content, and the signoff. The same applies to Slack, Teams, and the like. You can omit the greeting & signoff or keep them in, but you can't omit the content!
If you do, I'll wait until the next day or so, and if I remember I'll reply that they seem to have forgotten to include a message before hitting "send".
The best time to start fighting was 2015. The second best time is now.
Decently readable, though some of the letter forms you've chosen could be confused for others ('a' is quite similar to 'o', 'f' could be confused for 't'). When I'm lettering for engineering/math I use engineering gothic letterforms which avoid these ambiguities, among others (I vs l vs ι vs 1 vs 7, a vs α vs o vs ο, O vs 0, q vs g, k vs κ, v vs ν, u vs μ, B vs 8). When I'm handwriting I just write chickenscratch unreadable to anyone else including my future self after a year or so.

It's very slow, but some people made a RISC-V rv32ima emulator that runs on an ATMega328P to run Linux on an Arduino Uno. Nobody would do that in a commercial product (it's ridiculously slow, difficult, and further into "for shits & giggles" than Taco bell with laughing gas), but even the cheap shitty microcontrollers can run Linux. Badly.
Perl users don't have souls.
Not exactly a datastructure alone, but bitslicing is a neat trick to turn some variable-time operations into constant-time operations. Used in cryptography for "substitution box" (S-box) operations, which can otherwise leak secrets via data-dependent timing variations.
The datastructure side of it is breaking up n words into bits and interleaving them within n variables (usually machine registers), so that the first variable contains the first bit from each word, the second variable the second bit, etc. It's also called "SIMD within a register".
Selling products below cost is legally anticompetitive behavior. Anticompetitive behavior is only illegal for monopolists, which Valve aren't. But they have been accused and sued, part of why those suits haven't lead to them being declared a monopoly is because they don't engage in enough anticompetitive practices. So adding anticompetitive practices would be extremely risky for Valve.
