Why criticized, Elon Musk fired the engineer from Twitter.

According to international media, Eric, an engineer who works on the Twitter application on mobile phones, wrote in response to a tweet by Elon Musk that his understanding of the technical part of the app was wrong.

Elon Musk responded to the company's engineer, asking him that Twitter is very slow on Android, what have you done to fix it?

Eric took to several tweets to explain to Elon Musk, to which one user wrote, "Why didn't you tell your new boss all this privately?

To a user question, Eric, who has worked for Twitter for over 8 years, replied that maybe they should ask me personally.

Following the post, Elon Musk announced on Monday that Eric had been fired, after which Eric retweeted the Twitter chief's post with a salute emoji.

According to foreign media, several employees who were fired from Twitter this month used the salute emoji in their posts.

According to reports, this whole thing between Elon Musk and Eric started after Elon Musk on Sunday apologized for Twitter being extremely slow in several countries.

Hours after Elon Musk's tweet, Eric tweeted, "I spent 6 years working for Twitter and I can say it's wrong."
