Fastmail provides an easy way to migrate [0]. I setup a label in my Fastmail account that will tag all mail coming in from Gmail. Then you go through that list at your leisure and make the requisite contact with the people or services emailing at the old address. It's really not difficult at all. I've been on Fastmail for ~4 years now, and haven't once considered looking back or regretted it. Good luck.
So if they are using information people freely share to social media sites as the seeds for their investigatory and enforcement actions it follows that there is a simple trick people can employ or minimize their effectiveness.
They do, but some seem to be gradually removing functionality (like check deposit via scan + upload) in favor of using their amazingly convenient (/s) app.
Yes, I have direct first-hand experience with the "presenting one thing in initial talks pre-signature, and getting something completely different later" with the "big consulting firms". We spoke with actual senior engineers with highly relevant experience up front, and the dev team they sent to us to actually do work (completely with entire suite of product, ux, qa, etc etc etc...packing as many as possible) were people of a...lesser experience level. I'm being polite here.
I have a friend working in the business side of one of the large consulting firms, and the insight I got there is that sales is ahead of engineering staffing by _a lot_. In other words, the supply is being outstripped by the demand. Not wanting to leave money on the table these firms (or at least the very large "name brand" one my friend works for) will sign for projects which they do not have bench staff to fill. They then hit the streets and hire whoever can walk and chew gum at the same time.
Now we have to work alongside these people, who themselves are not so much to blame in many cases. They are pawns in the often-fraudulent game called Software Consulting, Inc. It's great fun. I feel for you.
