Same dev and they're both based on old newgrounds flash animations/games.
They've been slowly rolling it out for the last few months, I haven't been hit with it yet either.
If it's so annoying why not just block the sub? Open source isn't inherently bad or good.
You sound like you've gotta unplug a bit because this is clearly bothering you a lot, go enjoy your games the way you want to.
Agreed, I've been using refind for about a year now and it hasn't failed me.
I installed Windows on an isolated drive, connected another drive, installed Linux and refind.
running a quick refind-install in the terminal picked up the windows bootloader and all of the Linux kernels that I have installed.
Came here to recommend the same thing. Incredibly relaxing, funny, and wholesome.
