It shouldn’t. Older mags with poor tolerances and poorly designed followers used to have this issue and that is where people got into the habit of saying/doing/teaching that. Newer mags with better openings and followers no longer have this issue. This is true for both the AR and the AK platforms, the two most popular platforms in the world.
Also depending on how often it is “used” When I did my conscription service in Norway we had G3 magazines with ammunition issued for sentry duty. That is the same magazines were kept in the camp guard office and then handed over to whoever was going out for sentry duty. (But you used your own weapon) There were always a full squad of 10 + 1 sergeant and 2 officer on duty. So 13 magazines.
Once I was on duty I counted the rounds and the spring was so broken from the constant tension it was only able to lift the five first cartridges. Then the sergeant checked the rest and all were broken. We tried actual loading and about five cartridges were chambered.
End of semi pointless story? My boredom created a new SOP for guard magazines.
