At last, some authority talking sense!

If they weren't doing anything wrong they shouldn't care who watches where they go, right?
Fair enough. I could be happy to purchase if given more/better options. In fact, having the ability to do business from different platforms or self host is smart. Not having all your eggs in one basket is preferable. I was speaking more to people/businesses that rely on Facebook as their singular point of business. And my pet peeve that frustrates to the maximum is business support solely on X/Twit - That is so low effort and unprofessional.
Last time I looked it didn't -https://posteo.de/en/site/faq. However, Tuta does - https://tuta.com/blog/posts/own-domain-email. To refocus on OP's question, I would be happy to get a "professional business email" from a Posteo address.
Posteo is great for business. It's a professional and competent company that respects your privacy to a good degree, and has a clue about security. In a sense it's MORE professional than trying to DIY, unless you really know what you're doing. I would feel encouraged to see a business use Posteo when I receive the email. It tells me that your business probably cares a little about security and/or privacy and possibly the environment too. Total kudos for using Posteo from me.
What I think is completely unprofessional is to use your ISP's address for business email. The number one unprofessional business move, in my opinion, is to have your business website on Facebook/Meta, Twitter or any other enshitified corporate social media site. You won't get my business. I'll go anywhere else no matter how inconvenient.
See, you educated yourself! I only wanted to point you to official documentation with the hope you get in the habit of starting there (with any tech). Ask a hundred people and probably get a hundred differing answers. Look at Stack Overflow and sites like that where there's always multiple answers. Thankfully there's usually one with a green tick that is likely the best answer. Anyway, you now have it in a nutshell - No data to recover = The point of using Tails (without persistence). There's no such thing as permanent total online anonymity.
I think the first responder @grant did understand and answered in a relevant way. I'll answer your question with a question. What is the point of using VPN if your ISP can correlate times from logs? I think you should get on the Tails site and educate yourself further to better understand use case for Tails.
So yeah, I've heard it was a good movie too. Like, totally an Oscar worthy performance for sure! ;)
We`re never going to escape it, but I hope it's not as prevalent as it is on Facebook and twitter etc. Last time I heard anything about the topic regarding those platforms it was some surprisingly unimaginable number of corporate accounts. Like 75%. What I mean by that is people being hired by corporations to join social media platforms and pretend to be legit users interacting with others while pushing agendas, attending to damage control or recommending product.
I totally agree with the title's sentiment. I don't mind some free open source rough edges. Lemmy functions great. There's also a good deal of what looks like genuine interaction. However, I would like to point out that I think there's a LOT of corporate shills pushing agendas. Some notable ones might be pharmaceutical propaganda and corporate banking with cashless solutions.
Google's modus operandi - business as usual. Deploying their dirty tricks on their mass of servers to edge out and destroy competition. When caught out they apologize all surprised Pikachu style, then do it again differently. This is likely in response to news about Firefox mobile finally allowing extensions to work. People are probably trying it out, but their Youtube experience will be crap, so they'll go back to chrome.
This seems like a win for "civil society". Putting a dent in NSO's secrecy so software makers can patch against it would be a win as long as Whatsapp (Meta) publish their findings publicly and not keep it for themselves to be the next biggest threat to "civil society". As if they haven't done enough civil damage and spying themselves already.
