>It’s an absolute right, and one of the main points of GDPR, unless there are another law[0] stating that you can keep it, for a specific reason.
It can't be "an absolute right... unless", it's either absolute or it's not.
And if you read Article 14 the first paragraph says that "The data subject shall have the right to obtain from the controller the erasure of personal data concerning him or her without undue delay and the controller shall have the obligation to erase personal data without undue delay where one of the following grounds applies" (emphasis mine) and then lists six grounds. Further to that, paragraph 3 dis-applies paragraph 1 for more reasons than "another law states you can keep it".
>The company doesn’t own your data, you do.
Data controllers do own the data (insofar as one can "own" data), but data subjects have rights over the processing of those data that limit what the controllers may do with them.
