Someone else won't make it because they already have this for free. Well for this particular case, I think having Google product might just be better than none. But for some more critical things like typhoon warning, when people actually make decision based on data from the system, relying on a product that might get killed 5, 10 years later is worse.

If your infra is critical enough, they should nationalized, publicly owned.

Local government is disincentivized to build a system because they already has something up for free from the Big Tech.

Case in point: No one built a group-chat for our government officials cause Telegram is free.

Local governments are unable to do it right because, well, they are bureaucrats who cant differentiate the left hand from their right hand. Governments IT systems are eternal money sink holes only producing power points and weekly status reports to be forever forgotten.
