No. Payment channels are not centralized. Here you go again, trying to spread FUD in regards to something which you do not understand. Seems like you're part of the DunningKruger effect as described by the troll above me.
in another topic lauda pretended LN doesnt use hubs..
now he is saying there are no central intermediataries..
here i have done a screenshot a video from a video on a website lauda himself linked as his fountain off knowledge
hubs and intermediaries...
im guessing he will rebut talking about the spokes.. (users sending transactions) but will pretend the hub(intermediary) doesnt exist. and yet its this intermediary that actually works as a "mempool" and does the closing of the channel and settling the final large transaction..
i wonder what would happen if someone DDoSed the hub(intermediary) before it had a chance to settle... by by transactions
