Keep in mind although everything here
seems to be factual (I havent tested it myself yet), this is from Codeium, a company who could be incentivized to make Copilot look worse, as that could convince other companies use Codeium instead of Copilot.
That being said, I do generally agree with what Codeium says in their blog posts, such as Be Careful Where you Send Your Code [1]. Though that post's primary purpose seems to be to advertise the on-prem solution for enterprises, it makes some valid points. Despite some minor concerns, I like Codeium as a company—as a privacy-respecting alternative to GitHub Copilot—and would like to see them suceed.
