Singaporeans' use of the words "Mature" & "Matured" is Wrong

Are Singaporeans the only ones doing this? Unable to use these words correctly?

"Matured" is the past tense of "mature". "Mature" is an adjective.

Example: This wine has matured.
Example: He looks mature.
Example: He has matured over the years.
Example: Mature housing estates need to be revamped.
Example: Are you mature enough to be doing this?

Stop being an imbecile & use these 2 words correctly. Don't anyhow add a "d".

Even though I don't get paid correcting people's English (& why should I bother? Let them continue being wrong.), reading a Singapore news "article" online with the wrong words gets on my nerves & I have to finally say something about it.  Don't news articles have proofreaders? Editors? 

The wrong usage of the 2 words has been going on for a long time, especially in Singaporean conversations. Annoying. It's just simple English. Can't you get it right?
