In most of your examples the customers were not harmed and in some of them even the investors were made whole. A lot of people faced criminal investigation for their actions. This is what I mean when I say scams are incentivised. When a project you hold gets rugpulled, you have two choices: either hunt down the people who scammed you and get your money back (unlikely), OR shill your coin to as many people you can with the hope that some other greater fool will agree to hold your bags. Most crypto communities chose option B. Some even go as far as to defend the rugpullers so as to restore some legitimacy to the coin. The celcius people are a good example of this, but any bsc shitcoin will have the same process.
