I mean, they kind of have to be pretty good to entice you into the walled garden to begin with. Get people in the door with a smooth, super-polished experience, and then you’ve already got plenty of them pretty well won over. You’ll lose some users with previous experience with another OS to “It doesn’t work the way it did on $ancient_version of $OS, I hate it,” that go back, some just get tired of the same thing and want to try something new, and others that hit the walls of the garden and decide they want out. If it was straight garbage and restrictive, on top of being expensive, nobody would hang around until they got comfortable enough that overcoming the friction of changing was a real obstacle to switching.
There’s just a disproportionate representation of folks like myself in tech communities versus the general population who are opposed to any walled garden, no matter how polished, when there exist a free alternative.
You can go the nuclear option. My mother used to complain constantly that her computer was slow, and could I take a look at it. This developed into a fortnightly ritual where I would remove the Internet Explorer toolbars she’d added that took up a full third of her laptop’s screen, then run an antivirus scan for 5 hours or so to remove the malware she kept re-installing. Eventually, I got tired of it and told her I would either install something she couldn’t mess up as easily, or she could fix her own problems going forward. She agreed to trying something new, and her laptop got a nice Linux Mint install. I guess she really loved her malware, as she soon lost interest in the laptop, despite offers to show her how to do what she wanted to, which really weren’t more elaborate than opening Firefox and going to her email, facebook, etc, but I guess a new desktop icon and no toolbars was a bridge too far for her.
