Elon has the right to do what he wants as he spent a lot of money to buy Twitter.
However, the insensitive manner in which he did it shows a lack of human empathy. The bird is dead the culture is destroyed. The massive cuts are due to the extra 13 billion debt Elon has shoved on Twitter. Simply showing up with a sink and within a week firing 3700 people. No human empathy. Also the my way or the highway approach of Elon got another 1000 or so to leave. Twitter had problems and could have been run better no doubt. A 3 year profit plan and new CEO not Parag with a Vision and sales experience. A trim of 15% of staff who were lower performers, and a cut back in OPEX and CAPEX is such as outsourcing some functions, making employees pay for food and shrinking real-estate is all that it would have taken. Twitter was its people most were hardworking some lazy. The Borg has taken over attracting trolls and chasing away left of center types who made twitter. Advertisers have fled and subscription will take years to take off. He will not make it without a bankruptcy which is 6 months away. Because he cant pay his debt
