The "this isn't new it's always been happening" talk is disingenuous and incorrect. Yes, there has been some evidence of insider trading over the previous years. However, the scope and frequency of evidence pointing to insider trading since the Trump administration took power is orders of magnitude larger than was happening previously.
The 2020 insider trading scandal dealt with amounts in the hundreds of thousands and low millions. The sudden trading happening right before Trump makes announcements that majorly affect the stock market is in the hundreds of millions.
This isn't business as usual.
