Yes, in a sense, but not really. Let me explain.

We all make incoming liquidity possible, so in that sense it's competition.

However, LN+ provides it for free, and you "pay" with your own channel, so it's a different model for different situations. I think both models have a place when building up and operating a lightning node.

I think these services are complimentary and we all help LN grow which benefits us all: the services, LN users, humanity in general.
