It's not like they cheated you about being closed source, even if their co-founder BTChip still claims they are more open than Trezor
You seem to be very much confused buddy....ledger is already closed source device, and model X is not good wallet at all.
Data collection is probably happening for most wallets, but problem with ledger is they could be selling your data to third party, and all that can be seen in their privacy policy page:
