Even if you are an indie creator that makes something because they love it, you need to understand business because in order to have as much time as possible and the best tools to use on the thing you love so much, you have to get some kind of income from it or you can't put food on your table.
I believe Tapas is a company originally built out of love and genuine care for the webcomic business, and now it's just trying to find more methods to keep this project they love alive. If they lose income, that means staff members will gradually have to be kicked out to find jobs elsewhere. If staff drops out, the site gradually dies.
It has been mentioned but it's worth mentioning again: Ad revenue IS NOT ENOUGH. It's dropping faster than a goat trying to fly, and so will the income the site gains if they don't explore other opportunities of making an income.
It's a matter of not putting all your eggs in one basket, and as much as I love tapas, that goes for us creators too. If you aren't finding enough success on Tapas due to algorithms, then I'm sorry but you have a choice to make. Either you remain a hobbyist and do whatever the hell you want with it, or if you want to approach a professional route you need to explore as many other opportunities as you need in order to find what works for you. Don't rely entirely on Tapas if you're not a premium creator because Tapas does not rely entirely on you. There are more sites out there.
As of right now there are two ways to go about it that are more commonly successful than others. (Assuming you already make good content at a good rate)
1. Become a contracted creator of some sort, whether it be on webtoons or tapas
2. Be a free creator and have multiple mirrors of your comic on as many sites as it takes to widen your net.
You're not illoyal or some coldhearted person who's only out for the money just because you're looking for ways to make the money that you need. You're just a passionate person doing what it takes to keep what you love alive another year, and I would argue that this is what tapas is currently doing too.
