It’s kinda politics, as in Portugal, for instance, you can get a subsidy on pretty much any EV except for a Tesla - and it’s hard to see that as anything other than politically motivated.
Not politics, as I suspect you are probably aware.
In Portugal, electric vehicle (EV) subsidies are available for new battery electric vehicles (BEVs) priced up to €62,500, including VAT. This means that higher-priced models, such as Tesla vehicles, do not qualify for these incentives.
The primary reason for this price cap is to ensure that public funds are used to make EVs more accessible to a broader segment of the population, rather than subsidizing luxury vehicles.
There are many other incentives by the government, like not paying Vehicle Tax since they do not produce emissions. The incentives are listed here in the page of Tesla Portugal: https://www.tesla.com/pt_pt/support/incentives
