Why do people say its spoiling?

Everyone doesn't have as much free time as you seem to have.

If you have so little free time, then you probably shouldn't be doing content on day 1. You should be waiting until it's a breeze.

The point is that it's called a "blind run" not a "stupid run". So if you get kicked because you tell that dude who died 10 times already to avoid an AoE, then something is wrong within this community.

Besides, a "blind run" doesn't mean that the mechanics never get explained. If you absolutly want zero advice for the whole run, then turn off your chat, but don't start wasting people's time just because you're selfish and want to figure out yourself why the whole raid wiped 4 times on the same boss. Enough is enough.

So, no, someone shouldn't have to wait a month before playing a new patch just because people aren't able to figure out mechanics by themselves within an acceptable time.
There's a limit on how much people should be entitled/selfish.

The rule should be: people shouldn't explain the strat before the first pull, but don't expect them to hold their tongue after a few wipes or if they still see the same people getting killed.
It's called a compromise. A thing that a lot of players don't seem to know about.

TIL: A day is a month.

This. It's the best of both sides. When problems happen, you can give advice or come up with a strategy to clear. If the same player(s) keeps doing the same thing despite that advice, then that's really what a Vote Kick should be for (or an Abandon). But there isn't a need to explain mechanics straight off the bat. Do a pull and see how it goes.

If you want complete control over the random people you are going to do content with, then Party Finder is far more successful at achieving that. Obviously, with 24-man content this is much less useful. But it's not like the success of 24-man content is inherent upon every single player performing the mechanics. It is possible to clear it with less.

TIL: People clear the new 24-raid like "it's a breeze" after a single a day.
