When the Runner draws, they can draw in one turn, then spend the next turn pootling around playing cards, running and doing things other than drawing. To be honest against Jinteki, the drawing of Runner cards tends to be more clumped than against most factions anyway, like drawing up after hitting a Snare!
When the Corp installs, they can choose to install once per turn, rather than all at once.
The Corp can choose to maximise the ETF bonus. The Runner can choose to minimise the Palana Foods bonus.
Not to mention that the bonus in each case is the same: credits.
ETF can happily run a deck that leverages having a lot of money. If you are running your Palana Foods deck to have a load of net damage (so that you are making the most of your ability by encouraging the Runner to draw on as many turns as possible) you have a deck dedicated to damaging the Runner. But wait, it's a deck dedicated to leveraging money, since that's the bonus we're getting! It's going to be more challenging to fit both of those competing interests into a game plan. Do you want to leverage cards, or credits?
