I always see takes like this when people discuss alternative platforms. This is almost never the actual reason why people don't switch. The real reason is that most modern internet users are incredibly afraid of using a web browser - anything that isn't an official app is sketchy to them.
They have been entirely socially conditioned to think that looking for "alternative to x" or "free version of x" will give them an adware extension. Google knowingly promotes adware sites to any 8 year old who wants to get Minecraft for free, so they learn young that you can never trust alternative online services for anything. If a person makes it to 10 and is unable to find emuparadise, they will be afraid of any online 'alternative' for the rest of their lives.
