Github editor autocorrect causes between 5 and 10 keystokes per line to be wasted

[GeneralGuy4872]

2.1 : does not allow double lines
2.2 : moves curly brackets around
2.3 : indents lines strangely
2.4 : randomly converts tabs to spaces
and other various mangling of document layout vis-a-vis mistreatment of whitespace, some of which can be corrected, some is immideately reverted after being fixed
2.5 : syntax highlighting does not match gitattributes language, or filetype (style highlighting while editing C documents interprets # as comment instead of macro, fixed when only viewing file...usually)
2.6 : final line of document is covered by horizontal scrollbar, oscillates up and down rapidly while typeing
2.7 : control characters are changed to unicode substitution character when opening a file to edit it, massive data loss possible

I do not want these clippy-ish behaviors anywhere near my code space. I guess I should go back to using nano and vim and pushing my commits
