Tesco is paying shareholders £900m in dividends while enjoying £585m from the government
Well, then I expect them to deliver £585m in shares to the government by the end of the week, in lieu of a refund of the cash they were given. The government cash is meant to keep the business from going bust so that it can survive and participate in the normal risk / reward sector of the economy again afterwards. It's not a free reward for shareholders because the risk materialised. Behaviour like this is also not going to be looked upon well by the public if the damage causes mass hardship and executive snouts stay in the trough.
