I did address your point several times and I won't do it again.
The show never gave a reason why the characters in it would hate Goku that isn't petty. All the reasons you named are fans giving reasons to the characters that they never once stated. "They could live for another 1000 years", literally no one in the show said this, not even Gowasu who saw 1000 years into the future. "Zen'o could have forgetting", again, no one claimed this. It's the opposite since the Grand Priest explicitly said that Zen'o often talked about too many universes. "If they had more time, they could have raised the mortal ranking", true if those universes knew they're mortal ranking was so low and they didn't until the tournament was announce. Even then, they could have tried to asked Zen'o to postpone as Khai himself said, but the gods couldn't get their shit together. Overall, the characters in the show has no real reason to blame or hate Goku since even if he was reckless and careless with dealing with Zen'o, his action in the end ending up being a benefit to them. Instead of taking it as a blessing, they chose to bitch about it, mostly because Goku is even friends with Zen'o, hence the show presented them as petty.
Your argument amounts to 'characters could feel this way', yet you still haven't presented me with a character that has actually voiced these feelings. Only, 'well they could'. Also, this is a story, a work of fiction. It doesn't need to show me how everyone in the multiverse thinks. If the story wanted to present the argument that Goku's actions kept people from existing for another 1000 years or whatever and people are mad about that, they would have done it.
