When I choose to use wallet A, does Electrum broadcast the private key to the server also from wallet B if I don't 'activate' it?
Your private keys are never broadcasted to the server. You sign your transactions locally in your own device.
Apologies, I meant my public keys, xPub? The ones where you derive the addresses from.
So the server can see my addresses derived from a given XPub key whenever I use the wallet and thus can link those addresses.
But does my wallet broadcast xPub keys from both of the wallets within Electrum?
Standard wallets with different seeds produce different public keys, correct?

Can macs run Electrum Personal Servers? Are they easy to set up and run?
Does your Mac run 24/7? Technically an Electrum server doesn't need to run 24/7, but if not you'll always need to wait for it to be fully synchronized again.
Indeed my mac is offline most of the day. How long would it take to sync at 50Mpbs?
Are there any known pro-privacy advocates who run Electrum Servers that I could connect to?
For a node for dummies, how much would the set-up cost be and are they really easy to run?
I'm really liking this wallet and the old-school feel and design, and would love to use it as my lightning wallet if I can let it trust me.
Personally I don't think a smartphone is a suitable platform for cryptocurrency wallets, maybe except if you use them together with a hardware wallet that secures the private keys. With all the daily "shit" we do on our mobiles, I'd only put no more money in my Android wallet than I usually put in my fiat wallet (normally two-digit Euro/US-$ amounts, rarely more).
Agree with you on that. I am using cold storage.
But as for hot wallets on mobile with the way LN and other developments are advancing, it's becoming neat to have some sats ready to go.
I'm probably about 90% open source on my Graphene and I try to restrict my phone activities as much as I can.
I'm considering device isolation as well.
you can enable "Label Sync" plugin in the settings so that when you restore the wallet from seed, it'll restore the labels as well.
The downside is your data will be stored (encrypted) to a central server.
Right, btw what is the encryption and would you worry about it?
