I didn't mean to imply Steemit was going after me :)
We just couldn't find a way on how to proceed with the python-steem library jointly and thus decided to make a clear cut. In the end, having multiple companies following their own branding only benefits the whole community and Steem development. We've seen that already with busy.com, and we now see it with piston, both are strong brands and it would be a shame to not grow these brands independently.
