Usability.

Windows and Mac are both easier to use for the standard user.

Not at all true anymore for Windoze. Windows 7 was the last installment where that was true. Linux distributions are consistent. Once shown how the basics works, e.g., apt install or pacman -S and the general whereabouts of settings or software, it’s super easy to get them going, indefinitely. Even troubleshooting is within reach because searching the settings isn’t a maze within a maze (except for Gnome sometimes). Windoze keeps changing shit constantly, reinstalls uninstalled software, search algorithm is horrible and has Bing search results within the menu enabled by default [the fuck?], updates don’t indicate how long they’ll last, setting a default program often requires configuring it manually for every file extension, oh goddamn fuckers I have to stop typing because Microsoft pisses me off so bad.
Tabula rasa, if I had to teach a 70-year-old who’s never touched a computer before, to do so, I’d pick Linux every time. Consistency and customization is key. Microsoft makes their users dumb by an illusion of convenience which shatters the instant something goes wrong, like riding a bike with helper wheels that constantly fail. Linux does none of that. It empowers users quite quickly by simply learning how to ride a bike properly. Sure, you fall every so often at the start, but that made mastery that much more satisfying.

Please sit down for what I’m about to tell you. When a Linux user communicates with someone using Windows, the Linux user’s sent data is still being harvested. 💢

1 MB file size limit. That’s officially worse than email. Ridiculous.
And 100 MB if I pay? Wtf, what year is this, 2002?

It’s reality. They’re not using ads or any other unethical means of profit seeking. Imagine if everyone started using Matrix and no one paid, where do you suppose the money should come from to pay for the servers? It’s like going to the grocery store and being outraged that fruit has a price tag; “what the fuck, I can’t just take this?”

Also, I can’t remember ever sending files nearing 100 ㎆ via chat. Just use a cloud service and send the URL.

All these free services have made us spoiled, lazy, and greedy. I’ve written some related essay about it:

What if I paid for all my free software?
I’ve always felt guilty by taking for granted the rare breed of virtuous humans that provide free excellent software without relying on advertising. Let’s change that and pay, how much would I “lose” anyway? —https://www.arscyni.cc/file/take_my_money.html
