It's not like the tech industry is exactly new to using competing companies products.
Microsoft using Mac (not even discretely).
Apple using AWS, Google Cloud, Azure
Amazon Selling competing products

This may be a bit of a specialized case, but if you run a cloud hosting provider that is not your primary (or original) business you will need to accept that likely be involved in running a competing service. (I am sure AWS hosts a fair number of retailers and related technology)
