It doesn’t change magically. It changes through continuous usage and acceptance from society. That’s how language works.

Some examples. When was the last time you heard somebody say something was “awful”, as in awe inspiring? When a kid says literally, do you take them 100% seriously or do you accept that the word’s changed to be a synonym for “figuratively” among younger people? And as far as spelling is concerned, colour and color are both correct spellings, depending on where you live. Gray vs grey, acknowledgment vs acknowledgement, same thing. Or look at barbecue vs barbeque; the latter was incorrect for a very long time until the popularization of the abbreviation BBQ, after which it became a commonly accepted variant.

These things were not always correct, and yet, now they are. Society adopts and uses different meanings and spellings for words all the time. That’s how language works. Sorry friend, you’re not the arbiter of English. It changes with or without you onboard.
