My main gripe with Google Lens is that it replaced Google Image Search on their browser. Used to be able to drag/drop an image into Google and it’d do an instant search for all similar/identical images. Now it opens Google Lens and it just gives me a bunch of “related links” instead of a proper image search.
To get the old functionality back, I need to use a “Google image search” add-on in my Firefox browser. It opens the old Google image search page.
I mostly use it to find higher resolution versions of old, grainy images, but Google Lens took that functionality away from me.
In the US, you can register here to “reduce promotional mail offers from companies or organizations you don’t have a business relationship with.” It costs $4 ($5 if you opt to mail in a form instead of filling out the online form), but it registers you for 10 years.
I did this about 7 years ago and I haven’t seen any junk mail since. I added my wife’s name under the “add another version of your name” section (you can have 5 alternate names listed) and junk mail to her stopped too.
I’m gonna take a step back and introduce a more commonly heard/understood term. According to Merriam-Webster, a FEDERATION is:
an encompassing political or societal entity formed by uniting smaller or more localized entities: such as
a. a federal government
b. a union of organizations
Definition 1b. best sums up a federated system in the sense of OP’s question. It’s a collection of smaller independent organizations united for a particular cause. In the case of Lemmy and other federated sites, sharing digital information. No single federated site controls all of the “fediverse,” yet they can all technically communicate with each other as if they’re one entity.
Defederated, on the other hand, is just the opposite. A single centralized organization with complete control over the content they provide. Reddit, being one corporation that has complete control over all content on their own servers, is a defederated site.
