Nintendo has a long history of screwing over and treating third-party developers like their personal lapdogs. Their corporate attitude at the time was that they controlled gaming and could do anything they wanted.

Most of that video has been proven false, exaggerated or manipulated though. 

Nintendo's relation with third party studios is just fine. They published and marketed Monster Hunter and Yokai Watch in the West, They used Bandai Namco to develop Super Smash Bros. 4 and Pokkén Tournament (two big successes for the company), They financed Bayonetta 2 when no other company would, they turned Next Level Games from a mediocre developer into a good one (just compare their Nintendo games with their multiplatform games), they fixed the mess that was going on at Retro Studios in the early days and heavily influenced the direction of Metroid Prime (scan visors, FPS instead of Third Person, etc.), they gave a big project to Tantalus Media (Twilight Princess HD) and they only work on Nintendo-related projects these days (Switch ports for Sonic Mania and Rime), Good-Feel and Grezzo have also prosperred under Nintendo (Grezzo has even been allowed the freedom to make a new IP for Nintendo, Ever Oasis), etc.  

Did you really miss when I said "at the time"?

We've already had this exact same subject thread about 3 times already. Nothing new has been offered to the table to boot.

Also 4 times of being an asshole in 20 years isn't as bad as what you see on here per week.

I believe this was debunked already.

I'll see if I can find the previous thread

There we go. It was posted quite recently as well.
