Why not?
Changes are expected when we are doing something and to prevent an unnecessary problem such as complaints, it is important for the managers to make that statement.
That's all fine and dandy, but the problem is the project owners are starting to make changes like requiring kyc right at the end or reducing the payout to the bounty hunters...again, right at the end, after they've done all the advertising for the project. It's a statement that is being abused and it isn't fair to the bounty hunters.
Yes, I often see bounties like that, for example Mycro Jobs at the beginning of the bounty was launched. They did not say that following the bounty, they had to do KYC
And that's just one of a few examples I've seen of this. If the project can give a disclaimer like 'we reserve the right to change X' then at least they should be very clear about kyc requirements and state that the payment is fixed and not change it.
Until bounty hunters start standing up for themselves, this abuse will continue. It's good that op started a thread to address the issue.
