Why are WooThemes using TimThumb when even the developer of TimThumb doesnt use it, hadn't used it since before the 2011 exploit and there are better ways to do this?

This is what the TimThumb developer had to say:
"Don't use TimThumb"
"I no longer maintain it"
"there’s just better ways now"
"WordPress has had support for post thumbnails for ages now – and I use these all the time in my themes. I haven’t used TimThumb in a WordPress theme since before the previous TimThumb security exploit in 2011".

A few years ago, I became a full member of WooThemes, but I obtained a refund when I was told by
their staff that when they test their themes they do not have errors displayed and they do not check their error logs. I am sure they have improved since then.
