It is always work even if it’s a passion project.
People used to make shitty websites with good content but now they need to make good, professional looking websites for people to even look at them to decide on the whether the content was good.
This takes time and if you’re doing it for free then you’re choosing to do extra work on top of your day job.
As others have said, there are costs to hosting a website other than the time that you’re expecting people to give for free.
I was going to say “up to” £115k but it looks like most of them claim as close to the maximum that they think that they can justify.
I’d have thought that the costs would go down year after year as the financial impact on their lives went down over time. Theresa May’s is going up for some reason and why the hell are Tony Blair, John Major and Gordon Brown still claiming the full amount!?
