The majority of this data is generated via public funding. So over the crusty decades there have arisen public databases of notably varied quality, curation, and stability; e.g. GenBank, NCBI, SwissProt, EMBL, PIR, SBKB, PDB, ...quite a long list. (I've been involved in direct dealings with several of these sites and sometimes the histories and policies get very opaque)

Finally, the question: this is public data, (sometimes held in confidence but technically only for a "short" period), google is a private company, why should we place our trust in a for-profit organization to keep our public data publicly available without charging access fees? Admitting freely that having dealt for decades with the old model, i do have an open mind about this approach.
