Earlier quoted context omitted.
I like how you abbreviate "Microsoft" as "M$". It means you think of them without bias and with a clear head. /s
M$ has been a rather common abbreviation for Microsoft since at least slashdot days.
it's harder to type than just "MS" so when someone uses "M$" they go out of their way to signal that they are biased. Being biased is fine, so long as one understands that they are biased and that they are communicating their bias along with the rest of the message.
