Controversy on Vercel employee access to app data

So first Vercel opensourced his app ( similar)

Then they contacted him tho drop his domain, through his private email

I'm really wondering if employees are making moves based on customer data here.

1. see noticable trend of a customer app

2. Easy to do ( hard to master)?

3. Opensource a clone

4. Let Vercel tweet about it

5. Profit

This seems bad.
