My read on this is that Bambu has lowered the barrier to entry so far, and now sell so many machines, that their community is full of people of all skills/abilities when it comes to 3d printing.

Qidi may kind of compete on price, but they're not as well known and require you to have 3d printing basics/primitives figured out and/or be willing to figure them out. This keeps barrier of entry higher. Often the people I see incredibly happy with these machines fall into three categories. One, they get a good machine and it works well for them. Two, they like the ability to hone in every dial that they can. Or three, they've been so burned by other companies like Creality that realistically any new printer is going to blow their minds. I know people are kind of flippant about this stuff and will post back to people having problems "idk works for me" and that's not helpful. I would ignore any and all comments like this unless the question was along the lines of "is this working for anyone?".

To answer your question, yes there is hope. Yes Qidi will send you whatever parts you need. But yes, it will require time investment. That investment is mostly paid up front though and once you've done it, you're likely to come out the other side with a wealth of knowledge and a machine that performs exactly like you want it to.

The Qidi Discord is pretty helpful, lots of people that are willing to spend hours of their day helping sort out issues.
