Used in small doses to generate text with some degree of precision is helpful. I do find it to be a good way to cut out boring email writing. But I would recommend it more as a text generation tool than a fact generation tool. With the right expectations and work flow it fits right in. And no I don’t consider it plagiarism if the client’s demand is boring.
When not rooted I have two main free solutions.
You can use nextdns on your home network. They have around 200,000k free requests. For 2 people it seems to work out to around 20 days of ad blocks. This particularly helps with the ads on the TV as well.
Otherwise you have the options to use Firefox with extensions or Brave without (I know it’s not popular around here). You can also use ReVanced for youtube blocks.
For most usage that free combination suffices for me.
