There is a world beyond people who throw their notebook into the trash after 3 years. There are still plenty of users with 128 GB or even 64 GB. Now imagine Windows taking 30 GB out of these 64 before you even start installing any apps. Those people absolutely care about 500 MB.

Electron is also problematic for memory usage.

My main laptop has 4GB ram. I cannot afford to use 500mb for a chat app. Beside, did you even go outside? A lot of people cant afford (or dont need) a computer with more than that. For example lets see in a community where having a lot of ram matters. In the Steam Community, around 12% of people have 4GB or less. https://store.steampowered.com/hwsurvey#cat0_stats_row

I'll turn that question around. Wouldn't it be nice, not to mention cost-effective, to be able to do an office job on a Raspberry Pi? Fifty to seventy bucks a head, all in, and you have a machine that was plenty fast enough 15 years ago. When you commit to giant apps, you commit to hardware that costs twenty to fifty times that amount.

If you need more power, that's fine. But does an administrative assistant, or a lawyer, for that matter? Give me old-fashioned desktop applications, and I can compete with you at hundreds to thousands less per head. How many people doing that does it take to make a software engineer's time worth the trouble?

I do. Not necessarily because of dick space but because this bloat on applications with rather limited functionality usually comes with being memory hog, sluggishness and otherwise unpleasant experience.
