I do not hate when the project adds a few week's time, even without adding the allocation given from the beginning, whether it's to wait for softcap, or hardcap. however, promotion time is also important. some projects make the promotion for months, even they do it round and round. however, I remained supportive when it was only a few weeks. but, when it increased for several months for no apparent reason, I don't think I support it.
The right choice. We also need to think logically, extending the duration without a strong underlying reason can reduce the confidence of the bounty hunter, and of course that becomes a problem when the pool bounty is not added: D
Apart from that, before choosing to leave the campaign, make sure that the work we have done before can be saved. If not, then continue even with a heavy heart, hopefully we can get paid in kind.
Actually I am also not a problem with a long duration, as long as it is logical and in accordance with the roadmap related to the promotion and sales period and the rewards provided are comparable.
