High energy bills and misinformation about energy saving seems to be causing some odd behaviour here in the UK.
I have relatives who go round turning off every device and appliance at night, despite the negligible power draw they have in standby. Another will only charge their phone at night during cheaper the electricity rate - but runs the tumble dryer during the day.
I also often hear stories about people fearing electronic devices will catch fire if left on standby over night. Which may well be a risk for charging a dodgy Chinese e-bike but probably not for a home router.
I don’t think Mozilla running a Mastodon server is losing focus. The ethos of Mozilla and the Fediverse have a lot of overlap, and Mozilla should desire to have a foot in it.
An official Mastodon server is also a useful platform for marketing and outreach. In contrast an organisation claiming to be all about privacy and open source retreating from a social media platform that embodies those is not a good look.
