When people say "Indie Animation is beating Corpos', "Indie Animation is the only way now" or "Long Live Indie Animation", they're really only referring to Glitch, and there's a good reason: compared to other Indie Animation studios, they're practically the only ones to have achieved this status. The creator of Lackadaisy knew this, and that's why he allowed Glitch to buy his show; otherwise, it would have faded into obscurity.
Seriously, look at everything else we have: Lackadaisy is theirs now, so it doesn't count anymore. Vivziepop is reaching lolcow status as many people are losing respect for her due to the terrible decisions she makes on her shows (and because, in general, she's a terrible person), to the point that the Homestuck pilot received mixed to negative reviews, even though she had no involvement in the production beyond financing it. Everything else has cult following or is straight up obscure: There's Monkey Wrench, which I keep forgeting; it's mentioned often, but it seems like nobody really cares outside of its small group of fans. I bet the creator would like to pull a Lackadaisy and let Glitch buy his series too. I mean, just look at this:
There's Space King, which I haven't seen yet, but I've heard good things about it. However, it's not very popular; the mainstream isn't interested. Everything else is hit or miss; many pilots come and go every month, most fail and fade into obscurity. Some get short-lived fanbases like that Pretty Please I Don't Want to be a Magical Girl thing. I remember that the main character received a lot of fanart earlier this year, especially crossover fan art where she appears alongside Pomni and the Murder Drones characters, but after a month, everyone forgot about it. And then there is the black sheep of the Indie Renaissance: Skibidi Toilet. Seriously, Skibidi Toilet has grown and changed a lot; it has surprisingly good cinematography and animation, and now, DaFuq!?boom! is expanding the brand. He posted this on his Community tab a few days ago:

It's a real shame that Skibidi Toilet is still known in the mainstream as that stupid old meme of the SFM toilets (One thing I should mention is that they stopped animating in SFM and now animate in Unreal Engine, although they still use the SFM assets), completely unaware that it has lore or even a plot. And, to be honest, Skibidi Toilet made the transition from funny to serious much better than SMG4. In fact, I dare to say that Skibidi Toilet takes itself much more seriously than stuff like Murder Drones.
