Many small companies or even developers have clear and clean websites.
It's not a question of money. It's a question of taste.
Pragmatically though, it will always come down to money. Apple sure wants you to believe it's a matter of taste though, rest assured their marketing spend reflects that.
Having said that both Microsoft and Google have a decent range of hardware products as well. From Xbox to Pixels. Money shouldn't be a blocker for either of these tech companies.
The reality is, nobody has hardware margins like Apple. They sell an iPhone at full price, they pocket 40% of the MSRP. Part of those proceeds go towards marketing new iPhones, whereas Microsoft and Google don't really get the yields to justify that. Just look at the 2022 earnings call and you'll see how wide the disparity is.
