You didn't answer my question breh, but I guess I get what you're getting at, and I don't deny the possibility. Honestly I don't trust 10b5-1 plans, and believe there are many incidents of some abuse of it. All of these regulations enacted by the SEC are drafted by attorneys with incentives. This rule is intended to protect insiders from accusations of insider trading
. Also, according to Wiki: "After Rule 10b5-1 was enacted, the SEC staff publicly took the position that canceling a planned trade made under the safe harbor does not constitute insider trading, even if the person was aware of the inside information when canceling the trade."
I could go on and on about 10b5-1 plans, but I will leave this here for anyone who wants to read more.
