YABU.
I do think the government should be helping out people with Oil heating, in the short term.
Heating oil is usually used because there is no option for gas, which would be subject to a price cap, so it makes that fairer.
Also, you can't buy just a little bit of oil, due to minimum orders, so users are looking at several hundreds more at once, with no pay-monthly option. People do plan and budget, but personally, I plan assuming 65p or less, not 1.40+.
Finally, people with heating oil are often in the far north of the country, where it is colder. When prices spiked, I reduced my thermostat to 16c and to two hours per day. The temperature dropped to 10c some days. It's up to about 16c now, but due to get colder next week.
I can absorb the cost, and also stand the cold. But I do think vulnerable and elderly people should get help. Even just over the next few months, and hopefully people will be able to save for next winter or prices will drop.
