It's really not an equivalent situation. The problem with Intel and Microsoft is that their contributions defined the end-user application compatibility layer of the IBM product and they became indispensable brands of their own. No such equivalent exists for LG and GM. LG is just a replaceable commodity parts supplier. Bolt owners largely don't know or care about who supplies the battery pack and the pack charges using standard plug interfaces.
All the premium electronics on the Bolt are LG including infotainment and telemetrics.
I think it is better chance than not that most owners will know it is "LG Inside" as much as some Ram owners know they have a Cummins Turbodiesel.
I am not so sure LG is easily replaceable either. They have contracts through 2019. I don't see anyone else offering a lower price for the Bolt BEV kit currently supplied by LG. I don't see LG splitting the kit apart and offering cells below $145 per kWh.I think in 2020 LG will have more demand for their packs/cells than they have capacity. It will be a sellers not a buyers market.
I have seen more than a few Toyota RAV4s with home made "Tesla Inside" decals on their CUVs.
