Neither. It's a product of technology. Many of the people quibbling over spellings and sentence structure that in no way shape or form inhibits your understanding of what they say had to write their english papers out by hand or type them on older platforms.
Kids nowadays have everything on a computer and spell check is everywhere. The words get through because they are the correct spelling of a different word.
It's similar to what went on 40 or so years ago when calculators came out and slide rules went out of the wayside. The old guard then talked about how the kids were deficient because they couldn't instantly call up 14 x 19 or have a firm grasp of logs. They were irked too.
It's interesting the patterns humans circle around.
