Ex-Chicagoan here. This is absolutely, positively not a joke. I can probably come up with a half dozen schemes that would use the fiber build-out as a thinly-veiled excuse to bleed both Google and city residents.
Let's try.
1. All network providers would be allowed to charge a new "infrastructure maintenance fee" to their customers. A fixed $2, plus 40% of the amount of the fee, would go to the city per customer-month. Most of the amount collected would go to a maintenance contractor chosen through a "competitive" bidding process.
2. Public schools, municipal offices, police stations, fire stations, and public libraries would be required to buy network access through a single company, who would also manage their public wi-fi access points. That company could strongarm the providers into selling at a discount, due to its size, yet would charge the municipal customers a grossly inflated price. The wi-fi service sucks for everyone.
3. All fiber work done on city or RTA property must be done by union members, CWA or IBEW, according to their local worksite rules.
4. An alderman stalls the fiber authorization measure in committee until receiving sufficient "lobbying" to move it along.
5. Google required to lay far more dark fibers than strictly necessary. Unknown parties light some up for their own uses, without paying.
6. Google required to give CPD special access to network, supposedly in order to combat CP and terr'ism. Special access instead used to run untraceable server to sell items out of the evidence lockups.
