Of course players can still grind for donor ranks and buy them with grass if they wish, just like Krissy has mentioned. I just think that having obtainable ranks would be a good thing for both default ranked and donor ranked players. Donor ranked players would still be able to obtain the exact same obtainable ranks however Donor perks are likely to remain a lot better than the obtainable rank perks. All Skyblock has become about is having a nice island, making grass and selling items. Due to this players lose motivation to play more quickly. Implementing obtainable ranks is a win-win situation and gives both Donors and default ranked players incentive to play. It's a really good idea to reward players for all of their hard work without having real money involved.
