I can't speak for others but it is true for myself.

Higher fees will make me keep my BTC on custodial wallets rather than on chain.

I don't remember the specifics, so I might be wrong, but sats in a lightning wallet, like WoS, is still custodial even though they are Bitcoins. They are mine, but the node closing down or whatever may prevent me from being able to access those funds.

My practice is to move sats from lightning wallets to my own storage occasionally. Think of it like sats in a lightning wallet is like cash in your wallet that you carry around. you can pay out of it easily and put money in easily. on chain storage is like putting cash in a safe in your home. Not as easy to get money in and out.

So if fees are high, I might not move money as often. Fees will fluctuate and perhaps go up over time. That's natural and expected. I think it is important to understand why it is going up and whether or not those reasons are good for BTC in the long run.
