Don’t wanna be a grammar nazi, but seeing {if} and {would} in the same sentence is just painful, even tho I’m not a native English speaker.
And I’m sure this rule applies to a vast majority of languages around the world.
To answer your question, Reddit is already going public and is getting an IPO later this year, so I don’t think it would be drastically different from now, except we’d see the Meta logo everywhere.
I don’t think its really a very strong rule tbh, if it is one. I’m a native english speaker and I hear people say if before would all the time.
In the sentence in question, “were to” would probably work better, but mainly as would had already been used earlier, and it feels clunky repeating it.
“If you would do x for me, that’d be great.” Good example of an if before a would.
