You guys are welcome to unfollow and not support any dev or person you dont feel deserves it. That is absolutely, 100% your right to do so, and I absolutely encourage it. As it does show what you want to support. Thats the great thing about Patreon and Subscribestar, your money goes where you want it.
However, No one has the right to belittle others for reserving their right to support something they judge to be worth that cost.
As to a Dev putting their updates and communications behind a paywall. Not only is that their right, and as stated above, you have every right to disagree, but it makes Fiscal Sense for them to do so.
