When he was the franchisee of Cha Time, he went behind his partner in Taiwan to use cheaper local ingredients instead of buying from them and possibly also underpaying royalties. He then played victim when his contract got terminated and got local social media sites to back him up. One that exposed the full story got shut down (the story that is, i think the site is still around). He immediately launched Tealive which let many to suspect he already planned to stab them in the back for some time

He also stole the slogan  Never Bully The Weak, Fear the Strong from a local company

Also stole a marketing idea from an interview candidate (spoiler, they never hired her) and when the issue blew up, i think they offer to pay her in vouchers or something.

Is he that cheap skate? Possible, rumour has it the company in charge of their IPO is being paid in...stock options hahah

Anyway this might get reported so if mods want to feel free to delete. I hear he's got a lot of pull with influencers and social media news websites
