Some of the people who oppose the FRR are trying to create a barrier to entry (and reduce competition) by requiring that people either 1) spend a lot of time manually entering offers, or 2) learn how to program a bot.
Do you have any evidence of that, or are you just speculating about motives?
You can always set auto-lend at the lowest fixed rate you're willing to accept, which will then match the highest available swap demand. This may even be a better deal than the FRR for smaller lenders, since their funds won't end up sitting idle.
That said, I'd like to see better options available for lazy lenders. I am one, after all.
