DCL for a long time has had boutique, Palo Remy, Cabanas, no one forces anyone to purchase these. When a Cabana came in, no one was forced off a beach, we have free soda with meals and the self service station, but a charge at bars.
They have " added" services, nothing is taken away.
They have added options, similar to a mini bar in a hotel room, or hotel room service. Some will pay, most will not.
Some here post emotive posts well I wouldn't pay that for some fries, well you do not have to, some will not pay $590 for a cabana or $600 for a princess package, but some do. Concierge costs more, no one is forced to pay for it.
DCL is looking at increasing non fare income, that may keep fare costs down but give greater return for them. If they biked more net income they may get sign off, for more new ships.
So additional services that are optional are put down with some posts, it has not changed what you get in return for your cruise fare.
This is a storm in a tea cup whipped up by a few, like paying for water, that's been with DCL fir ever, unless you say tap water which remains free.
If you do not agree, cruise RCI then get nickel and dimed in fact fined is a better word.
