Why?

[mathieucarbou]

Is there an alternative or backward compatibility "path" for pioarduino users ?

rename

[Jason2866]

Rename every appearance of Platformio to pioarduino
PIO is no trademark and can never be one since it is a usual term for Parallel Input Output
Both files are mandantory and needed to build support for pioarduinoand only should be renamed

[TD-er]

since it is a usual term for Parallel Input Output

... or Programmable Input/Output.
Which only makes your point even stronger. :)

Well remembers me of my beginning with computers the first PIO i used was from Zilog for the Z80 https://www.zilog.com/docs/z80/ps0180.pdf

pioarduino has PIO word... it may be a problem.

Let's talk.

I don't think so. PIO as abbreviation was long before the Platformio company has seen the light. It is commonly used and stands for Programmed Input Output in technical terms.
So Platformio can not claim a trademark or brand on PIO
In pioarduino pio stands for People Initiated Optimized Arduino. There is no relation to anything.
Clearly no reference to pio or try to trademark https://piolabs.com/legal/trademarks.html#the-marks

Closed as it won't be changed by now.
