A few thoughts here might help you: #55695

The trick on Stacker News is to create posts that bring value to other people. When you create "question" posts, then those are usually not as valuable, unless the question is particularly good and even then the "answers" usually get more sats overall.

For example this question would not be considered that great, because you have not clarified at all what you mean and you have not shown that you actually tried answering that question yourself.

If you mean "can anyone can change the code you run without your permission?" the answer is: no if you use a non-custodial wallet, yes if you use a custodial wallet.

If you mean "is the lightning network protocol set in stone?" the answer is no. Protocol changes are proposed regularly and wallet makers tend to implement them in a gradual manner. The mechanisms for upgrading the lightning protocol are similar to how bitcoin updates get approved, except in lightning there are fewer core developers and its stability is not as important as bitcoin's. These things make it easier for changes to happen quickly but it also means there is more trust placed in core developers.
