It turns out that save for a small, if vocal, snippet of the community, players are actually happy with the business model GTA Online works with, at least in the face of the alternatives. As often as we might see complaining about Shark Cards and in-game prices on community sites, the fans still prefer this over paid DLC.
As a response to some vocal criticism of Rockstar's handling of the GTA Online business model, namely the 'drip feeding' of weekly DLC packets in between major releases, we kicked off a poll asking players which business model they would see as ideal for GTA Online, including the current one which is implemented and a number of alternatives which would still provide Rockstar with a revenue stream to fund the development of DLC.
In total, we gave six options, but the current DLC and Shark Card model won with over 50% of the votes total, making it clear that the majority of players prefer this model over any of the others proposed. The second runner-up was a skewed model where all DLC was paid but at a very low price, in exchange for the lowering of in-game prices.
While the current model winning out wasn't ultimately a surprise — you can't make over $500 million in revenue off a system that the majority dislikes — we were surprised by the ranking of the other proposed solutions, such as paid cosmetic goods being the least popular option.

Indirectly, this poll goes to show the massive divide between the hardcore and casual gaming crowds, who seemingly not only differ in tastes for games, but tastes for DLC models as well. The prevailing opinion among hardcore players is that when a game has paid content, the best possible option is to include premium cosmetic items.
This way you have access to all the meaningful content without additional payment, and the premium content is entirely optional because it does not influence gameplay, balance or anything at all beyond what you look like in the virtual world.
Even the ever-hated freemium "pay to win" model got more votes in the poll which is baffling at first, but when we remember that casual freemium mobile games make even more cash than GTA 5 does it becomes apparent that the model in question isn't as widely condemned as we'd think.
