I can agree with you. Projects tends to postpone their ICOs because of the pandemic. Which one reason is it's a scam. Because more people will be interested on investing on a ICO. "But why would you postpone the ICO if a lot of people will be investing?" Good question. The answer is just simply more people who are experienced in investing in this kinds will know if they are a scam. But this just a speculation of course. Maybe the project isn't ready because they lack man power.
