First of all, Easement, nearly always NOT Right of Way, there is a difference. Right of Way is owned by, well, it's owner, the county, the gas company, the power company, ect. Easement is right to Use, but not ownership.
In as close to 100% as possible of cases, the power easement, power company is responsible for maintenance, as they require. So, keeping trees back as required for aerial clearance, mowing for access, but not mowing for the sake of mowing or mowing for looks, thats not them.
Easements are a contract, Which requires a transfer of money or other things of value. So, they may have paid at one point to purchase rights, or it could be (often is) a requirement to provide service. Them providing service to you had value.
Then we have public ROW use permits. Generally, and I mean generally, utilities do not pay a lease or annual or anything fee for utilities in public ROW, because it is a benefit to the people of the state (local laws vary, so maybe a couple states require a "franchise fee" for use of the ROW).
No utilities, no homes, and no anything. Wr can scream about them forcing Easements or sales, but you can't have a home without power, can't have a business or anything without power.
